ADDITIONS AND CORRECTIONS
During the considerable interval of time since the printing of this work was commenced, many additional facts have come to light in regard to the habits and geographical distribution of the land birds of North America; and while several so-called species have proved to be mere races, or even of less rank, some others have been added to the list. The more important of these are herewith subjoined.
Most of the new facts here announced are the results of the more recent labors of Captain Charles Bendire, First Cavalry, U. S. A., and of Messrs. J. A. Allen, C. E. Aiken, Dr. E. Coues, H. W. Henshaw, Mr. C. J. Maynard, and others, whose names are mentioned in their appropriate places.
Turdus pallasi, var. nanus (I, 20). Dr. Cooper has sent to the Smithsonian Institution skins of his T. nanus, and they prove to be T. ustulatus. The surmise expressed on page 21, that the nest and eggs described by Dr. Cooper as those of the former in reality belonged to the latter species, is thus undoubtedly correct.
Turdus pallasi, var. auduboni (I, 21). A nest with the eggs (S. I. 16,320) of this species was taken near Fort Ellis, Montana, July 16, 1872, by C. H. Merriam, attached to Dr. Hayden’s party. The nest is large and bulky for the size of the bird, is deeply saucer-shaped in form, measuring 6 inches in external diameter by 3 in depth. The cavity of the nest is 3 inches in diameter by about 1.75 deep. It is composed entirely of green mosses and lined with fine grass leaves.
The eggs were three in number, in shape broadly ovate and obtusely rounded at either end. They measure .85 of an inch in length by .72 in breadth; their color is a rather deep greenish-blue, almost exactly like those of Turdus migratorius.
The nest was built in a small pine-tree, about eight feet from the ground, in the pine regions of the mountains. In its position it differs from any now known of the Turdus pallasi, which, so far as known, builds invariably on the ground.
Harporhynchus ocellatus (I, 36). This is probably a Mexican form of H. cinereus.
Harporhynchus rufus (I, 37). According to Mr. Allen (Bull. Mus. Comp. Zoöl., Vol. III, No. 6, p. 134) this species is found on the eastern slope of the Rocky Mountains in Colorado. It is not included in the “Birds of California,” but Dr. Cooper states that in September, 1870, he found a straggler at Clear Lake, close to the lower town. It was in a thicket with its western cousins, but possessed unmistakably all the characteristics of the eastern bird. Unfortunately, it was not secured. As this species is short-winged and nearly resident in many localities, its occurrence so far from its usual resort is somewhat remarkable. It had none of the appearance of a cage-bird.
Harporhynchus curvirostris, var. palmeri (I, 43). Four specimens from Tucson, Arizona, were recently forwarded for examination by Dr. Coues, collected by the indefatigable Captain Bendire, U. S. A., when stationed at that post. The specimens are all true palmeri in the characters which definitely separate it from curvirostris, its nearest ally, and show the seasonal discrepancies in the shades of color. A male and female, collected in November, differ from the types, which are summer birds, in being of a brownish-plumbeous above, even more ashy than in any specimens of curvirostris which we have seen. In all other respects, however, they are typical examples of var. palmeri, and substantiate the validity of this well-marked form. The measurements of these two specimens are as follows:—
♂. Wing, 4.50; tail, 4.90; culmen, 1.45; tarsus, 1.25; middle toe, 1.00.
♀. Wing, 4.20; tail, 4.80; culmen, 1.40; tarsus, 1.20; middle toe, .90.
The description of this form was first published by Dr. Coues in “Key to North American Birds” (October, 1872), p. 351, the type being specimen No. 61,589, Mus. S. I.
Harporhynchus bendirei, Coues (Am. Nat. Vol. VII, June, 1873, p. 330, fig. 69).
Char. Nearly similar to H. palmeri in color, but whiter on the breast, and apparently more ochraceous on the flanks. Much smaller than H. palmeri, with smaller and very differently shaped bill. Male (not adult), No. 2,686, Mus. E. C. Wing, 4.10; tail, 4.50; culmen, 1.15; tarsus, 1.20; middle toe, .88. Female (adult), No. 2,688, Mus. E. C. Wing, 3.80; tail, 4.40; culmen, 1.15; tarsus, 1.15; middle toe, .88.
Hab. Tucson, Arizona.
This new form Dr. Coues considers to be most nearly related to the H. cinereus of Cape St. Lucas; and judging from its eggs, lately sent to the Smithsonian Institution by Captain Bendire, such appear to be really its affinities.
The eggs sent by Captain Bendire (No. 16,486, Mus. S. I.) measure 1.00 in length by .80 in breadth, and are three in number. Their ground-color is a dull bluish-white, spotted with a very faint shade of reddish-brown, the spots thickest round the larger end.
Harporhynchus crissalis (I, 47). Captain Bendire found this species breeding abundantly near Tucson, Arizona (See Coues, Am. Nat. VI, June, 1872, 370). The eggs in all instances were similar to those described as found by Dr. Palmer, unspotted, and in size, shape, and color, hardly distinguishable from the eggs of the common Robin (T. migratorius). They are of an oblong-oval shape, rounded and nearly equal at either end, and measure 1.10 inches in length by .75 in breadth.

Harporhynchus redivivus.
Harporhynchus redivivus (I, 45). The accompanying cut, showing the extreme anatomy of the species, was omitted in its proper place.
Mimus polyglottus (I, 49). Mr. C. E. Aiken has obtained this species in El Paso County, Colorado.
Saxicola œnanthe (I, 60). Mr. C. J. Hampton obtained a specimen of this bird at Junius, Seneca County, N. Y., on the 9th of September, 1872. Professor Newton suggests, by letter, as an interesting problem, the route by which this species reaches Alaska in its migrations. It is not known to occur near the Sea of Ochotsk, has not been found on the Lower Amoor, and probably does not occur farther eastward than the Baikal Mountains. It has never been noticed in Japan or on the coast of China. It must therefore be very nearly certain that it cannot take that way to Alaska. Sundeval states that it is found in Kamtschatka, but this Mr. Newton questions, as no authority is given for this statement. The only alternative is to assume a route via Greenland, in this, perhaps, in a measure indorsing Petermann’s suggestion that Greenland extends across the pole nearly to the Asiatic coast and to Alaska.
Sialia mexicana (I, 65). This species has been obtained in Western Iowa by Mr. Atkinson.
Regulus calendula (I, 75). We present the outlines of bill, feet, wings, and tail, omitted in their proper place.
28782
Regulus calendula.
Polioptila cærulea (I, 78). Mr. Aiken has taken this species in El Paso County, Colorado. Dr. Cooper informs me that he found it quite numerous near Auburn, Placer County, Cal., May 11, 1870, apparently migrating northward. In the following December he saw one near San Francisco. From this he infers that it winters much farther to the north in that State than it does east of the Rocky Mountains, and that the individuals occurring in Guatemala are eastern birds. He also states that it is the prevailing and probably the only form in all the northern and western parts of the State of California. About September 20, 1872, this species came in great numbers to the vicinity of San Buenaventura and remained there all winter, going to the mountains northward by March 20.
Polioptila melanura (I, 81). Dr. Cooper informs me that while he found P. cærulea common in September, he saw none of this species near San Buenaventura until November 12, when small parties appeared moving westward from the colder desert regions east of the mountains. They kept entirely in the artemisia thickets among the sandy and dryest tracts, never going into the high trees like P. cærulea. In form, color, restless habits, and scolding mew, this species is said to be a perfect miniature and mimic of the Catbird.
According to Captain Bendire the species is not common in Arizona, where he met with three nests. “One before me, found July 25, 1872, fastened in a bunch of mistletoe, or rather suspended in it, is composed of a species of wild hemp fibres nicely woven together, and lined with a few feathers and exceedingly fine grass.” The nest is very neatly made: Outer diameter, 2 inches; inner, 1.60; depth, 1.50. The number of eggs is five, ground-color pale green, with spots of light reddish-brown color scattered over the egg. Measurement, .50 by .40 of an inch. Their notes are a rather harsh twitter, kept up for some time. They are active little birds, and are very restless.
Chamæa fasciata (I, 84). Mr. Allen thinks that he saw this species in Colorado Territory. See Am. Nat. VI, June, 1872, and Bull. Mus. Comp. Zool. III, No. 6, p. 184.
Lophophanes inornatus (I, 91). Mr. Aiken has obtained this species in El Paso County, Colorado, where it is common, while Mr. Henshaw, the naturalist of Lieutenant Wheeler’s expedition, found it abundant in Southern Utah. These Rocky Mountain specimens are much grayer and somewhat larger than those from California.
Parus rufescens (I, 104). Nests and eggs of a Parus which undoubtedly belong to this species were found by Mr. William A. Cooper, at Santa Cruz, Cal. One of these nests, sent to the Smithsonian Institution, was found about four miles from Santa Cruz, April 22, 1873. The nest was composed of moss and fine bark, largely intermingled with the fur of rabbits and other small quadrupeds. It was built in a hole in the branch of a tree about ten feet from the ground. The branch was about half a foot in diameter and was partially decayed. The cavity was about a foot in length from the nest to the place where the bird gained an entrance, which was a small hole about an inch and a quarter in diameter. The eggs were seven in number and contained partially formed embryos. They measure .64 of an inch in length by .52 in breadth, resemble the eggs of the atricapillus, but are more sparingly marked with spots, rather more minute and of a lighter shade of reddish-brown, on a white ground.
Sitta pygmæa (I, 120). This bird is probably a geographical form of S. pusilla, as suggested by Mr. Allen (Bull. Mus. Comp. Zoöl., Vol. III, No. 6, p. 115).
Sitta pusilla (I, 122). Young specimens collected at Aiken, S. C., by Mr. C. H. Merriam, are quite different in color from the adult plumage. The head is pale dull ashy, instead of light hair-brown, and the colors are duller generally. There is a near approach to S. pygmæa in their appearance.
Campylorhynchus brunneicapillus (I, 132). This species has been collected at Toquerville, Southern Utah, by Mr. Henshaw, and in Southern Nevada by Mr. Bischoff, naturalists to Lieutenant Wheeler’s expedition.
Salpinctes obsoletus (I, 135). The range of this species has been remarkably extended by the capture of a specimen in Decatur County, Southern Iowa, where others were seen, by Mr. T. M. Trippe. See Proc. Boston Soc. N. H., December, 1872, p. 236.
Catherpes mexicanus, var. conspersus (I, 139). Numerous specimens obtained in Colorado by Mr. Allen and Mr. Aiken, and in Southern Utah by Mr. Henshaw, establish the fact of great uniformity in the characters of this race, and its distinctness from var. mexicanus. On page 139 “it is noticed that it is a remarkable fact that this northern race should be so much smaller than the Mexican one, especially in view of the fact that it is a resident bird in even the most northern parts of its ascertained habitat.” As we find this peculiarity exactly paralleled in the Thryothorus ludovicianus of the Atlantic States (see below), may not these facts point out a law to the effect that in species which belong to essentially tropical families, with only outlying genera or species in the temperate zone, the increase in size with latitude is toward the region of the highest development of the group?
Dr. Cooper met with two specimens of this species in California in 1872; one about twelve miles back of San Diego, the other the same distance back of San Buenaventura, and both at the foot of lofty, rugged mountains. Their song he compares to loud ringing laughter; it is so shrill as to be heard at quite a distance, and seems as if it must be produced by a much larger bird.
Thryothorus ludovicianus (I, 142). Specimens of this species from Miami, Fla., are much darker colored than those from the Middle States (Maryland, Illinois, and southward), as might be expected; but very strangely, they are also much larger. In colors they very nearly resemble var. berlandieri, from the Lower Rio Grande.
A specimen in Mr. Ridgway’s collection (No. 1,864, January 9), from Miami, Fla., compares with one from Southern Illinois (No. 1,652, Mt. Carmel, January, 1871) as follows:—
In coloration they are more nearly alike, the Florida specimen being hardly appreciably darker on the upper surface, though the lower parts are much deeper ochraceous, almost rufous. The Illinois specimen is deep ochraceous beneath, just about intermediate between Maryland and Florida specimens. Another Florida specimen (No. 62,733, Mus. S. I.; C. J. Maynard) measures: wing, 2.50; tail, 2.40; culmen, .85.
Thryothorus bewicki, var. leucogaster (I, 147). Specimens of this form were obtained at Toquerville, Southern Utah, in October, 1872, by Mr. Henshaw, attached to Lieutenant Wheeler’s expedition.
31045, ♂
Troglodytes parvulus, var. hyemalis.
Troglodytes parvulus, var. hyemalis (I, 155). Dr. Cooper has noticed a few of these Wrens near San Buenaventura in winter, after November 10. They probably reside in the summer in the high coast mountains lying east as well as in the Sierra Nevada. Outlines, omitted before, are here given.
Cistothorus stellaris (I, 159). Mr. Henshaw obtained good evidence of this bird’s breeding at Utah Lake. Nests and eggs were found in a farm-house, unquestionably those of this species, and said to have been obtained among the tulés or sedges along the shore of the lake. Outlines of this species are here given.
3073
Cistothorus stellaris.
Anthus ludovicianus (I, 171). Mr. Allen found this species breeding in the summer of 1871 on the summit of Mt. Lincoln, Colorado Territory, above the timber-line, at an altitude of over 13,000 feet.
Helmitherus vermivorus (I, 187). Professor Frank H. Snow procured a specimen of this species near Lawrence, Kansas, May 6, 1873.
Helmitherus swainsoni (I, 190). Was obtained in Florida by Mr. W. Thaxter.
Helminthophaga virginiæ (I, 199). Very common in El Paso County, Colorado, where it was obtained by Mr. Aiken.
Helminthophaga luciæ (I, 200). We are indebted to Captain Bendire for the discovery of the nest and eggs of this comparatively new Warbler. He first met with its nest near Tucson, Arizona, May 19, 1872. Unlike all the rest of this genus, which, so far as is known, build their nests on the ground, this species was found nesting something after the manner of the common Gray Creeper, between the loose bark and the trunk of a dead tree, a few feet from the ground. Except in their smaller size the eggs also bear a great resemblance to those of the Creeper. In shape they are nearly spherical, their ground is of a crystal whiteness, spotted, chiefly around the larger end, with fine dottings of a purplish-red. They measure .54 of an inch in length by .45 in breadth.
Helminthophaga celata, var. lutescens (I, 204). See Am. Nat. Vol. VII, October, 1873, p. 606.
Helminthophaga peregrina (I, 205). Obtained in El Paso County, Colorado, in September, 1873, by Mr. Aiken.
Parula americana (I, 208). Obtained in May in El Paso County, Colorado, by Mr. Aiken.
Dendroica vieilloti, var. bryanti (I, 218). See Am. Nat. VII, October, 1873, p. 606.
Dendroica auduboni (I, 229). In July, 1870, Dr. Cooper found families of this species fully fledged, wandering through the woods, at the summit pass of the Central Pacific Railroad, 7,000 feet altitude, confirming his supposition that they breed in the high Sierra Nevada. There they are very numerous in summer, following the retreating snow to this elevation about May 1, when the males are in full plumage, retaining it till August. Their song is always faint, and similar to that of D. æstiva.
Dendroica cærulea (I, 235). A nest, containing one egg, of the Cærulean Warbler, was obtained in June, 1873, by Frank S. Booth, the son of James Booth, Esq., the well-known taxidermist of Drummondville, Ontario, near Niagara Falls. The nest was built in a large oak-tree at the height of fifty feet or more from the ground. It was placed horizontally on the upper surface of a slender limb, between two small twigs, and the branch on which it was thus saddled was only an inch and a half in thickness. Being nine feet from the trunk of the tree, it was secured with great difficulty. The nest is a rather slender fabric, somewhat similar to the nest of the Redstart, and quite small for the bird. It has a diameter of 2½ inches, and is 1¼ inches in depth. Its cavity is 2 inches wide at the rim, and 1 inch in depth. The nest chiefly consists of a strong rim firmly woven of strips of fine bark, stems of grasses, and fine pine-needles, bound round with flaxen fibres of plants and wool. Around the base a few bits of hornets’ nests, mosses, and lichens are loosely fastened. The nest within is furnished with fine stems and needles, and the flooring is very thin and slight. The egg is somewhat similar in its general appearance to that of D. æstiva, but is smaller and with a ground-color of a different shade of greenish-white. It is oblong-oval in shape, and measures .70 of an inch in length by .50 in breadth. It is thinly marked over the greater portion of its surface with minute dottings of reddish-brown. A ring of confluent blotches of purple and reddish-brown surrounds the larger end.
Dendroica blackburniæ (I, 237). Obtained at Ogden, Utah, in September, 1871, by Mr. Allen (Bull. Mus. Comp. Zoöl. III, No. 5, p. 166).
Dendroica dominica (I, 240). A superb nest of the Yellow-throated Warbler was taken by Mr. Giles, near Wilmington, N. C., in the spring of 1872. The nest was enclosed in a pendent tuft of Spanish moss (Tillandsia usneoides), and completely hidden within it. Its form is cup-shaped, and it is made of fine roots, mixed with much downy material and a few soft feathers, and, except in its situation, does not differ much from other nests of this genus. Other nests have since been received from Mr. Giles; also a nest of Parula americana similarly situated. Mr. Ridgway, from an examination of the nests, infers that this situation is not constant, but that in other localities where the moss is not found this Warbler may build in thick tufts of leaves near the extremity of drooping branches, or in other similar situations.
Dendroica dominica, var. albilora (I, 241). See Am. Nat, VII, October, 1873, p. 606.
Dendroica graciæ, var. decora (I, 244). See Am. Nat. VII, October, 1873, p. 608.
Dendroica castanea (I, 251). This Warbler is cited by us as exceedingly rare in Eastern Massachusetts, though not unknown. A remarkable exception to this otherwise general rule occurred in the spring of 1872. For several days, in the latter part of May, they were found in great abundance in the vicinity of Boston. As the same unusual occurrence of this species in large numbers was noticed by Mr. Kumlien in Southern Wisconsin, it is probable that along the 42d parallel something occurred to cause a deviation from their usual migrations. The long pause of this species in its spring migrations, and its appearance in large numbers, are not known to have occurred before.
Mr. Salvin (Ibis, April, 1872) expresses the opinion that this Warbler, in its southern migration, does not pause in its flight from the Southern United States to stop in any of the West India Islands, nor in any point of Central America north of Costa Rica. It is by no means rare at Panama during the winter. We may therefore infer that in both its southern and its northern migrations long flights are made, at certain periods, over sections of country in which they do not appear at all, or where only a straggling few are ever seen, and that their abundance in 1872 was exceptional and due to causes not understood.
Dendroica nigrescens (I, 258). Obtained in El Paso County, Colorado; Aiken.
Dendroica occidentalis, D. townsendi, and D. nigrescens (I, 258, 265, 266). While travelling over the Cuyamaca Mountains east of San Diego, in April, 1872, Dr. Cooper found D. occidentalis, for the first time, quite common. They seemed to be still migrating during the last week of April, but perhaps were only moving upwards, being numerous between the elevation of 1,500 and 4,000 feet, while heavy frosts still occurred at the latter height. They probably go in May as high as 6,200 feet, the summits of the highest peaks, which are densely covered by coniferous trees. D. townsendi and D. nigrescens were in company with occidentalis in small flocks, among the oaks, and all seemed to be following an elevated route northward. In 1862, Dr. Cooper found them among the chaparral along the coast, but he regards this as exceptional and probably occasioned by a severe storm in the mountains, as he saw none in 1872 in a spring of average mildness. They occur about Petaluma as early as April 1.
Seiurus ludovicianus (I, 287). Mr. E. Ingersoll met with the nest and eggs of the Large-billed Thrush near Norwich, Conn. The nest was sunk in the ground, in some moss and in the rotten wood underneath the roots of a large tree on the banks of the Yantic River. It was covered over, except just in front, by the roots. The nest was 2½ inches in internal diameter and rather shallow, and was somewhat loosely constructed of fine dry grasses and little dead fibrous mosses. About the nest, but forming no part of it, were several loose leaves. These were chiefly in front of the nest, and served as a screen to conceal it and its occupant. The nest itself was placed under the edge of the bank, about ten feet above the water. The eggs were four in number and were quite fresh. Unblown, they have a beautiful rosy tint, the ground-color is a lustrous white, the egg having a polished surface. They are more or less profusely spotted all over with dots and specks, and a few obscure zigzag markings of reddish-brown of two shades, and umber, with faint touches of lilac and very pale washing of red. These markings are much more thickly distributed about the larger end, but nowhere form a ring. They resemble the eggs of S. aurocapillus, but differ in their somewhat rounder shape, the brilliant polish of their ground, and the greater distinctness of the markings. They varied from .75 to .80 of an inch in length, and from .60 to .62 in breadth.
Geothlypis (I, 295). For a new synopsis of all the species of this genus, see Am. Journ. Science and Arts, Vol. X, December, 1872.
Geothlypis trichas (I, 297). Dr. Cooper found this species wintering in large numbers near San Buenaventura. They frequented the driest as well as the wettest spots.
Geothlypis macgillivrayi (I, 303). We now consider this form a geographical race of S. philadelphia. (See Am. Journ. Science and Arts, Vol. X, December, 1872.)
Myiodioctes pusillus, var. pileolatus (I, 319). See Am. Nat. VII, October, 1873, p. 608.
Setophaga picta (I, 322). This species, not included in the preceding pages among North American Birds, was noticed on only two occasions by Captain Charles Bendire in the vicinity of Tucson, Arizona. This was on the 4th of April, and again on the 12th of September, 1872. He thinks that they unquestionably breed in the mountains to the northward of Tucson. When seen in September they appeared to be moving southward, on their way to their winter quarters. He saw none throughout the summer. (See Am. Nat. VII.) By letter from Mr. Henshaw, we learn that he has obtained this species at Apache, Arizona.
Vireosylvia olivacea (I, 369). Obtained at Ogden, Utah, in September, 1871, by Mr. Allen.
Lanivireo solitarius (I, 373). Dr. Cooper found, April 30, 1870, a male of this species in full plumage and singing delightfully on a ridge above Emigrant Gap on the west slope of the Sierra, about 5,500 feet altitude, and where the snow was still lying in deep drifts. He is confident that he saw the same species at Copperopolis in February, 1864. He thinks there is no doubt that to some extent they winter in the State.
Lanivireo solitarius, var. plumbeus (I, 378). El Paso County, Colorado; Aiken.
Vireo pusillus (I, 391). Dr. Cooper found this species near San Buenaventura as early as March 26, 1872, where it was quite common. On the 22d of April he found a nest pendent between the forks of a dead willow branch. This was five feet from the ground, built on the edge of a dense marshy thicket, of flat strips and fibres of bark, and lined with fine grass, hair, and feathers. There were a few feathers of the Barn Owl, also, on the outside. The nest measured three inches each way. The eggs were laid about the 28th, were four in number, white, with a few small black specks mostly near the larger ends, and measured .69 of an inch in length by .51 in breadth.
Phænopepla nitens (I, 405). Captain Bendire writes me that he found this species common in the vicinity of Tucson, Arizona, during the summer, a few only remaining during the winter; most of these had white edgings on all their feathers, and were probably young of the year. Their flight is described as wavering, something like that of Colaptes mexicanus. While flying they utter a high note, resembling whuif-whuif, repeated several times. He never heard them sing, as they are said to do, although he has watched them frequently. They are very restless, and are always found about the mistletoe, on the berries of which they feed almost exclusively. The nest is saddled on a horizontal branch, generally of a mesquite-tree. It is a shallow structure, about 4 inches across; its inner diameter is 2½ inches, depth ½ an inch. It is composed of fine sticks, fibres of plants, and lined with a little cottonwood down and a stray feather. The first nest was found May 16. This was principally lined with the shells of empty cocoons. The number of eggs was two. Though he found more than a dozen nests with eggs and young, he never found more than two in a nest. Their ground-color varies from a greenish-white to a lavender and a grayish-white, spotted all over with different shades of brown. The spots are all small, and most abundant about the larger end, and vary greatly in their distributions. In size they range from .97 of an inch to .84 in length, and in breadth from .66 to .60.
Collurio ludovicianus, var. robustus (I, 420). See Am. Nat. VII, October, 1873, p. 609.
Certhiola newtoni (I, 427). See Am. Nat. VII, October, 1873, p. 611.
Certhiola caboti (I, 427). See Am. Nat. VII, October, 1873, p. 612.
Certhiola barbadensis, Certhiola frontalis (I, 427). See Am. Nat. VII, October, 1873, p. 612.
Pyranga hepatica (I, 440). Captain Bendire found what he identified as this species breeding near Tucson, Arizona. Its nests and eggs resembled those of P. æstiva. The latter vary in length from 1.02 inches to .95, and in breadth from .70 to .67 of an inch. Their ground-color is a pale light green. Some are sparingly marked over the entire egg with very distinctive and conspicuous blotches of purplish-brown; others are covered more generally with finer dottings of the same hue, and these are so numerous as partly to obscure the ground. In shape the eggs are oblong oval, and are of nearly equal size at either end. This species was also obtained by Mr. Henshaw, at Apache, Arizona.
As no skins of the parent appear to have been preserved, it is not improbable that the bird in question may be really P. æstiva, var. cooperi.
Hesperiphona vespertina, var. montana (I, 450). Two adult males obtained at Waukegan, Illinois, in January, 1873, by Mr. Charles Douglass, are typical examples of the Rocky Mountain form.
Pinicola enucleator (I, 453). Dr. Cooper mentions having shot a fine male of this species near the summit of the Central Railroad Pass at an elevation of about 7,000 feet. It was in a fine orange-red plumage. It was moulting, and appeared to be a straggler.
Pyrrhula cassini (I, 457). Since the publication of the article on this species we learn from Cabanis (Journal für Ornithologie, 1871, 318, 1872, 315) that the species is not uncommon in the vicinity of Lake Baikal, in Siberia, and that it has even been observed in Belgium (Crommelin, Archives Neérlandaises). The bird, therefore, like the Phyllopneuste borealis (P. kennicotti, Baird) and Motacilla flava, is to be considered as Siberian, straggling to continental Alaska in the summer season.
Chrysomitris psaltria (I, 474). See Am. Journ. of Science and Arts, Vol. IV, December, 1872, for a special paper upon the races of this species and their relation to climatic regions.
Chrysomitris psaltria, var. arizonæ (I, 476). On the 7th of May, 1872, Dr. Cooper saw a single specimen (male), which he had no doubt was of this bird, at Encinetos Ranch, thirty miles north of San Diego. It was feeding with other species among dry sunflowers. He also saw another near San Buenaventura in January, 1873.
