1867.] MR. p. L. SCLATER ON CHILIAN BIRDS. 335 



(4) Chloephaga 2ioliocephaIa, Gray, MS. ; Sclater, P. Z, S. 1857, 

 p. 128 ; 1858, p. 290. — Bernida chiloensis, Ph. et Land. I. c. p. 195. 



I have ah-eady 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 specularis, King. 



4. Anas melanocephala, Vieill. ; Cassiu in Gilliss's Exp. 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 /. 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- 

 rhogaster, Meyen. 



6. Querquedula torquata (Vieill.). 



This species is not included by Gay in his work ; but there are 

 specimens in the Paris Museum, labelled " Cbiii (Gag).". 



7. Querquedula cyanoptera (Vieill.). 



8. Q. versicolor (Vieill.). 



9. Q. creccoides (King). 



Querquedula ff??^?/s^«>05^m, Phil, et Landb., Wiegm. Arch. 1863, 

 p. 202, from Peru, would appear to be Q. Jlavirostris (Vieill.) (ihe 

 true Anas oxypfera of Meyen), which is not the same as Q. crec- 

 coides. According to Hartlaub (Naum. 1853, p. 217) Q. Jlaviros- 

 tris 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. Dujila oxyura (Meyen). — Anas oxyura, Meyen; Cassin, 

 Gilliss's Exp. ii. p. 202 ; Burm. La Plata, Keise, ii. p. 515. 



Considered by Burmeister to be separable from, although nearly 

 allied to, the eastern A. spinicauda, Vieill. 



12. Spatula platalea (YieiW. ) = Rhynchaspis maculata, Jard. & 

 Selb. 



Of the group of Fuligulinse only one species seems to have been 

 recorded as common in Chili, Fuligula peposaca (Vieill.) {Anas 

 metopias, Poppig) ; but Micropterus cineretis 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. vittaia (Wiegm, Arch. 1860,
