3. Further Remarks on Fuligula nationi. By P. L. Sclater. 



[Keceived April 12, 1878.] 



(Plate XXXII.) 



Professor Nation of Lima, Peru, has now forwarded to me a 

 second specimen of the remarkable new Fuligula which Mr. Salvin 

 and I described in the Society's ' Proceedings' last year (1877, p. 

 522), and dedicated to its discoverer. This is a male, the former 

 example having been a female ; but, as will be seen on comparison, 

 there is not a great difference in plumage between the sexes. Prof. 

 Nation says that this bird is rare in the neighbourhood of Lima, but 

 that he has lately ascertained that it is common in the north of Peru, 

 and is found in great numbers on the lakes near the coast in certain 

 months of the year. 



The species may now be diagnosed more correctly as follows : — 



Fuligula nationi. (Plate XXXII.) 



Fusco-atra fere unicolor, in ventre brunnescentior, hypochondriis 

 et genis in brunneum transeuntibus ; secundariorum parte basali, 

 fasciam distinctam alarem constituente , alba ; subalaribus nigris ; 

 remigum pagina inferiore obscure cineracea ; rostro et pedibus 

 nigris: long, tota 18"0, alee 8"5, caudce2'o, tarsi 1*45, dig.med. 

 cum ungue 2'6, rostrl a rictu tin. dir. 22. Femina omnino
