354 ANATID^. 



The only specimens known of N. nationi are those mentioned 

 below, and I do not know whether those mentioned by MacFarlane 

 really belong to this species.

Keij to the Species. 



a. Speculum white, tipped with black. 



a' . Back and scapulars in adult males greyish 

 white, irregularly waved or zigzagged with 

 black ; no distinct crest ; abdomen white. 

 «". Plead, neck, and chest uniform black, the 



first with a dark green gloss marila, p. 355. 



b" . Head, neck, and chest unifoi-m black, the 



first with a purplish gloss affinis, p. 360. 



V . Back and scapulars in adult males black, 

 usually sprinkled with whitish. 

 c" . A long pendent occipital crest in adult 



males ; abdomen white fuligula, p. 363. 



plumage, the wings of the male are imperfect, the quills lost, and the speculum 

 not visible on any of the remaining feathers. 



"The most nearly allied species are Nyroca brimnea, Eyt., and Nyroca 

 imtioni, and from these the male hardly differs in plumage, inclining rather to 

 N. brimnea in colour than to N'. nationi. The sides of the head and upper 

 neck are rather lighter and redder, but this may be due to fading. The bill 

 and legs are now of a pale yellowish-brown ; in both N. brunnca and N. nationi 

 they are quite dark. In size the bill agrees very nearly with N. brunnca, but is 

 perhaps slightly higher at the base." 



According to Prince Neuwied : " iris vermilion-red ; bill at the tip of a 

 plumbeous colour, greenish olive on the basal portion ; the legs appear to have 

 been dull plumbeous." 



"The female agrees very closely with that of Nyroca brimnea. The distri- 

 bution of white on the face and throat is similar in the two birds, but less in 

 extent in N. crythrophthalma. The whole plumage, especially the under surface, 

 is more ferruginous, as is often the case in some specimens of AnatidiB. As in 

 the male, the bill and legs are now pale. The two birds are of the same size, 

 the wing in each case measuring about 8 inches."
