On the Birds of the Philippine Islands. 101 



" The female agrees very closely with that of Nyroca 

 brunnea. The distribution of white on the face and throat 

 is similar in the two birds, but less in extent in A. erythro- 

 phthalma. The whole plumage, especially the under surface, 

 is more ferruginous, as is often the case in some specimens 

 of Anatidee. 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. '^ 



The principal diiference between the type specimens of 

 A. erythrophthalma and N. brunnea and N. nationi is the 

 present pale colour of the bill and legs of the first, which no 

 doubt is due to fading, as we learn from Wied^s description 

 that the bill ivas plumbeous like the legs. 



After all this it seems extremely likely that the Brazilian 

 N. erythrophthalma ( Wied) , the Peruvian N. nationi, and the 

 African N. brunnea are one and the same species (which will 

 have to stand under the name of N. erythrophthalma) , common 

 to South America and South Africa. The case would be 

 similar to that of Dendrucycna viduata and D. fulva, which 

 are also found on both these continents, the latter species 

 extending even to India. Possibly Nyroca erythrophthalma 

 is only a straggler to South America, unless we are to believe 

 that the Ducks found, very common near Arica and Mollendo 

 by Mr. MacFarlane (Ibis, 1887, p. 203) really belong to 

 N. erythrophthalma.
