77. Heteronetta melanocephala (VieilL). 

 Heteronetta atricapilla, Salvad. B. M. C. xxvii. p. 325. 

 (Rio Pilmaiguen.) 



I got one example only of this Duck on the Rio Pilmaiguen, 

 Feb. 19th, 1890. I had not observed any like it before, so it 

 may be one of the numerous visitors which I was told come 

 to this locality in the cold season. 



78. Anas specularis. 



Anas specularis, Salvad. B. M. C. xxvii. p. 215. 



(Rio Pilmaiguen.) 



I first came on these birds at Rio Bueno, and do not 

 know how far they extend elsewhere, but they appear to be 

 well known. 



The correct Spanish name of this Duck is '' Pato anti- 

 ojillo" ( = Spectacle-Duck), but the natives about Rio Bueno 

 called it " Pato real,^' probably knowing nothing of spectacles, 

 and therefore not seeing the appropriate application of the 

 term to the peculiar face-markings of this species. 



A fine adult male measured 2 feet long ; bill 2'25 inches 

 to rictus, 1*9 to base of culmen. The legs and feet were 

 orange, the claws black at the tips ; the web between the 

 toes blackish. Iris black. Bill slate, almost plumbeous. 



I always found this Duck near the banks of the rivers 

 where shaded by the forest, and never on fields or open 

 marshes. It may be found on streams in the dense forest 

 where no other species occur. 



79. Anas cristata. 



A7ias cristata, Salvad. B. M. C. xxvii. p. 216. 



(Sacaya, Sitani, and Lake Huasco.) 



I found this species only in the Andes of Tarapacd, where 

 it was common enough, and was perhaps partially resident. 

 It nested at Huasco and Sacaya from January to March, in 

 sedge or rushes, preferring little islands in the midst of 

 ponds. As well as I could ascertain, the clutch is usually 

 five or six. 



The iris Chinese-orange. The flesh of this Duck is very 

 good eating.
