Original description.—“The bill is long, and straight almost to the point, where it is hooked or bent suddenly down, and sharp; the head and neck bare of feathers nearly down to the stomach, when the feathers begin to cover the skin, and soon become long and of a soft texture, forming a ruff or tippet, in which the bird, by contracting his neck, can hide that as well as his head; the bare skin on the neck appears loose and wrinkled, which is of a bright yellow colour, intermixed with coral red; the hinder part of the neck is nearly covered with short stiff hair; and the skin of this part of the neck is of a dun purple colour, gradually becoming red as it approaches the yellow of the sides and forepart. The crown of the head is red; there are lobed lappets of a reddish orange colour, which lay on the base of the upper mandible. The plumage of the bird is generally white or cream colour, except the quill feathers of the wings and two or three rows of the coverts, which are beautiful dark brown; the tail, which is rather large and white, is tipped with this dark brown or black; the legs and feet of a clear white; the eye is encircled with a gold coloured iris, the pupil black.” Bartram, as above, p. 150, 151.
Obs. The identification of the bird here described, may be considered as one of the most important services to be performed in North American Ornithology. Its occurrence has never been noticed since the time of the accurate and veracious naturalist who first described it, and his careful description above quoted seems to clearly indicate it to be a species entirely unknown. The white tail especially is characteristic, and establishes a clear distinction from any other known species. It is related evidently to the King Vulture, (S. papa,) but that species has a black tail, and in case of mistake or misprint in Bartram’s description, it may be presumed at any rate to relate to an occurrence of that species within the United States. There is no more inviting nor more singular problem in North American Ornithology.

SPECIES, THE OCCURRENCE OF WHICH IN THE UNITED STATES IS DOUBTFUL.
1. Sarcoramphus gryphus. (Linn.) The Condor.
Bonap. Am. Orn. IV. pl. 22. Temm. pl. col. 133, 408, 464. Zool. Voy. Bonité, Birds, pl. 2, (Paris, 1841.)
Size, large. Head, neck, and large space on the breast, bare. Plumage, black, with a white space on the wing; neck, with a collar or ruff of white downy feathers; plumage of the back, the quills and tail frequently with a gray tinge. Head above with a large caruncle or comb, and others on the sides of the head and neck.
Total length of skin, about 4 feet, wing about 2 feet 6 inches, tail about 15 inches.
Hab. South America.
Obs. The famous Condor of the Andes, though it has been admitted as a North American bird into the works of Bonaparte and Nuttall, cannot at present, in our opinion, be so regarded. The description in the History of the Expedition of Lewis and Clarke, which was supposed to relate to this bird, and has been the sole authority for its introduction by the authors just mentioned, very probably applies to the Californian Vulture. No other travellers have seen the Condor, either at the localities mentioned by Lewis and Clarke, or elsewhere in North America. It is common in the western parts of South America. The most complete descriptions with which we are acquainted are by Humboldt, in Zoological Observations, I. p. 26, (Recuil d’Observationes de Zoologie et d’Anatomie comparée Paris, 1811, quarto,) and by Darwin in Zoology of the Voyage of the Beagle, Birds, p. 3, (London, 1841,) and by the same author in Voyage of a Naturalist, I. p. 234, 238, (American edition, New York, 1846, duodecimo.)
2. Sarcoramphus papa. (Linn.) The King Vulture.
Spix. Av. Bras. pl. 1. Buff. Pl. Enl. 428. Vieill. Gal. pl. 3.
Plumage on the neck, dusky cinereous; wings and tail, glossy black; all other parts, fine pale fulvous. Head and upper part of neck naked, the former with an elevated and conspicuous caruncle arising from the cere.
Total length of skin about 28 inches, wing 18, tail about 9 inches.
