Per. pp. 48, 279), from the highlands of Peru, which we believe to be the same as the present species. W e are not able to distinguish Mr. Whitely's skins from other examples from Chili and La Plata. Tschudi lays stress upon the presence of a black breast-band in his T. ingce ; but this band is also present in southern specimens. He also states that the white throat is peculiar to T. ctorbignyanus; but this is also present in one of Mr. Whitely's specimens. 55. RALLUS RYTHIRHYNCHUS, Vieill. Rallus rythirhynchus, Vieill. N.

S. 1867, p. 333. Rallus bicolor, Guy, Faun. Chil. Aves, p. 434. Aramides zelebori, Pelzeln, Novara-Reise, Vog. p. 133(?). After comparing Mr. Whitely's example of this Rail with specimens of Rallus sanguinolentus of Chili, and skins of the Rallus rythirhynchus of Buenos Ayres, we have come to the conclusion that they all belong to one rather variable species. The present example is shorter-billed than Mr. Salvin's specimen from Leybold, alluded to P. Z. S. 1867, p. 333. W e suspect that Von Pelzeln's A. zelebori is the same species from Southern Brazil. Rallus rythirhynchus must, however, be carefully distinguished from R. nigricans (= R. ccesius), with which some authors have confounded it, being at once recognizable by its incurved bill and the red spot at the base of the lower mandible. 56. ANAS CRISTATA (Gm.). Anas py r r hoy aster, Meyen, Nov. Act. xvi. Suppl. p. 119, t. 25. Several skins of both sexes of this fine species, which are coloured alike, obtained at Salinas (alt. 14,000 feet). 57. QUERQUEDULA OXYPTERA. Anas oxyptera, Meyen, Nov. Act. xvi. Suppl. p. 121, t. 26. Querquedula oxyptera, Tsch. F. P. pp. 55, 309. Querquedula angustirostris, Ph. et Landb. Wiegm. Arch. 1863 p. 202. One example from Salinas, the receipt of which has enabled us to clear up the confusion alluded to by Sclater in his notes on Chilian birds, antea, p. 335. There are two closely allied species of Querquedula- the present bird and Q. flavirostris (Vieill.). Messrs. Philippi and Landbeck have correctly pointed out the differences between them ; but they have renamed the present species, not under- |
