Show 1867.] MR. P. L. SCLATER ON CHILIAN BIRDS. 335 (4) Chloephaga poliocephala, Gray, MS. ; Sclater, P. Z. S. 1857, p. 128 ; 1858, p. 290.-Bernicla chiloensis, Ph. et Land. 1. c. p. 195. I have already given full notes on these species of Geese in some remarks on Messrs. Philippi and Landbeck's paper on this subject in the 'Ibis' for 1864 (pp. 121, 122), and need not repeat them now. The well-authenticated Chilian Freshwater Ducks are about twelve in number, namely :- 1. Mareca chiloensis (King). 2. Anas iopareia, Philippi, Wiegm. Arch. 1860, p. 24. I have not yet seen examples of this species. 3. Anas sjjecularis, King. 4. Anas melanocephala, Vieill.; Cassin in Gilliss'sExp. ii. p. 202, t. 25. Mr. Salvin has specimens of both sexes of this species, received from Herr Leybold. The male is well figured by Cassin I. c. The female has the throat white, the occiput blackish, and the sides of the head marbled with brown. 5. Anas cristata (Gm.) ; Gray, List of Anseres, p. 136 = A.pyr-rhoyaster, Meyen. 6. Querquedula torquata (Vieill.). This species is not included by Gay in his work ; but there are specimens in the Paris Museum, labelled " Chili (Gay).". 7. Querquedula cyanoptera (Vieill.). 8. Q. versicolor (Vieill.). 9. Q. creccoides (King). Querquedula angustirostris, Phil, et Landb., Wiegm. Arch. 1863, p. 202, from Peru, would appear to be Q. flavirostris (Vieill.) (the true Anas oxyptera of Meyen), which is not the same as Q. creccoides. According to Hartlaub (Naum. 1853, p. 217) Q. flavirostris also occurs in Chili; but there is some confusion between these two species, which I am not able to rectify for want of specimens. 10. Dafila bahamensis, Linn. 11. Dafila oxyura (Meyen). - Anas oxyura, Meyen ; Cassin, Gilliss's Exp. ii. p. 202 ; Burm. La Plata, Reise, ii. p. 515. Considered by Burmeister to be separable from, although nearly allied to, the eastern A. spinicauda, Vieill. 12. Spatula platalea (Vieill.) = Bhynchaspis maculata, Jard. & Selb. Of the group of Fuligulinae only one species seems to have been recorded as common in Chili, Fuligula peposaca (Vieill.) (Anas metopias, Poppig) ; but Micropterus cinereus also occurs in the southern provinces (Pelzeln, Novara-Reise, Aves, p. 139). Erismatura ferruginea, Eyton, is the only Chilian species of this genus I have met with. It inhabits the freshwater lakes of Central Chili, according to Gay. Philippi's E. vittata (Wiegm. Arch. 1860, |
