Genus : Nyroca 
Many authorities assign the Red-crested Pochard to the genus Netta, considering that 
with such distinctions as the tapering bill and short lamellcB it is entitled to generic rank. 
These features, however, do not seem to me to be sufficient, and I have in consequence 
included it in the genus Nyroca which also includes Ffiligula} 
In the matter of uniting Fuligula and Nyroca I follow Blanford, for the distinctions 
of the two genera as pointed out by Salvadori and others, such as the parallel sides of the 
bill in Nyroca and the wide bases of the bill in Fuligula, are very slight. Even these 
differences, Mr. Stuart Baker points out {Indian Dttcks, p. 233), are only a matter of degree, 
which he proves in the measurements of the bills of N. baeri and N. Africana. 
The genus Nyroca is a cosmopolitan one and contains seven species which are resident 
or migratory to Great Britain and Ireland, two of these being of such rarity or doubtful 
authenticity as to be hardly reckoned as British birds.

1 The latest classification of British birds is that found in the Hand-list of British Birds, by Messrs. E. Hartert, 
F. C. Jourdain, N. F. Ticehurst, and H. F. Witherby. This has appeared after the present work had gone to press. Mr. 
Hartert agrees with me that there are too many genera amongst the Ducks, but I completely fail to understand the arrangements 
by which the authors of the foregoing work include the Golden-Eye, Buffel-headed Duck, and Long-tailed Duck in Nyroca, 
and the Harlequin in Histriotticus. Steller's Eider, too, called an Eider, is also given a separate genera. 
2 Various other local German names are (translated) : Club-headed diving duck, Crest-headed, hooded, red-head, hooded- 
whistling, yellow tufted, great lake, fire, carmine, solitary, Turkish and Bismaten Duck (Naumann).
