Show 328 MR. P. L. SCLATER ON CHILIAN BIRDS. [Mar. 28, thentic specimens is Stenopsis bifasciata (Gould)*, of which I have skins sent by Mr. Leybold and Messrs. Philippi and Landbeck. The Caprimulgus andinus of the latter gentleman f is, as I have already suggested J, and can now state positively from the examination of marked specimens received from the describer, merely the young of S. bifasciata. Lesson has described a Capr. exilis from " Chili" (Rev. Zool. 1839, p. 45), but it is impossible to say what species he refers to. Fam. TROCHILIDAE. The Humming-birds found in Chili are three in number, namely- Oreotrochilus leucopleurus, Gould. Patagona gigas (Vieill.). Eustephanus galeritus (Mol.). Of these the Oreotrochilus belongs to a strictly Andean genus, of which the present bird is the most southern representative. Mr. Bridges describes it as inhabiting a zone of elevation of from 6000 to 8000 feet above the sea-level; but near Hueso Predo Dr. Philippi § assures us that it descends to 1000 feet above the sea-level. Patagona gigas, which is common in Central Chili, ranges as far north as Quito ; and Eustephanus galeritus southwards to Tierra del Fuego, and northwards to the vicinity of Lima in Peru. Fam. PICIDAE. Three Woodpeckers only, as far as I know, have been hitherto recorded as Chilian, namely Campephilus magellanicus^, Picus lignarius, and Colaptes pitius. Fam. PSITTACIDAE. Three species of Parrots are likewise certainly correctly assigned to Chili, namely Henicognathus leptorhynchus, Conurus cyanolyseos, and G. smaragdineus. Order ACCIPITRES. Fam. VULTURIDAE. Sarcorrhamphus gryphus and Cathartes aura are well known to be both abundant in Chile ; C. atratus is stated by Mr. Cassin (Gilliss's Exp. ii. p. 173) to be "occasionally met with in the interior," though Mr. Darwin says (Zool. Beagle, iii. p. 7) that he never observed it. The bird is certainly common in the vicinity of Mendoza (Darwin, I. c. p. 7), whence, Bridges also states, it sometimes crosses the frontier \ into the province of Colchagua. * Cf. P. Z.
