384 APPENDIX. 



Genus DAFILA. Typo by monotypy : J). acuta (Linn.). 

 Genus NETTA. Type by monotypy : N. rufina (Pall.). 



Genus NYROCA. Type by tautonymy : 3'. nyroca (Giildenst.). 

 If the White-eye and the Tufted Duck are considered 

 to be congeneric, the oldest name is Nyroca, 1822, 

 antedating Fuligula Stephens, 1824, by two years. In 

 the A. 0. U. Check-List Mania Oken is used, but the 

 same objections obtain as in the case of Qnerqiiedula. 



Nyroca nyroca. This name, published in 1770, has priority 

 over those of Gmelin (Anas ferruginea and A. africana) 

 published in 1779 and used in the 1st edition of the 

 List and by Salvador! in the Catalogue of Birds B. M. 

 respectively. 



Genus G-LAITCION. Type by monotypy : G. clan<inla 

 (Linn.). Clangula, the name commonly used for the 

 Golden-eye, dates from 1819, when it was published by 

 Leach (Ross Voy. Discovery, App. p. xlviii). The type 

 species on which this name was founded, was un- 

 doubtedly the Long-tailed Duck and not the Golden- 

 eye. 



In the A. 0. U. Check-List, Oken (Isis, 1817, p. 1183) 

 is quoted as the first notice of Clangula as a genus, but 

 a glance at Oken's paper will convince anyone that it is 

 impossible to consider the names there mentioned as 

 valid genera under Art. 25 of the international code. 

 The next name available, Glaucion, is here used. 



Glaucion clangula. The Golden-eye was first described in the 

 1758 edition of Linnaeus under the name Anas clangula. 

 In the 12th edition it is referred to twice, under the 

 names of A. clangula and A . glaucion, both on p. 201. 



Genus HISTRIONICUS. Type by original designation and 

 tautonymy : H. histriotucus (Linn.). This generic 

 name antedates Kaup's Cosmonetta, published in 1829, 

 and used in the 1st edition of the List.
