by tautonymy. Anas fuligula Linnaeus). 
; Ania BONAPARTE, Ann. Lyc. Nat. Hist. N. Y., IT, 1828, p. 386 (in synon-

naeus ). t 
Glaucium GRAY, List Genera Birds, 1840, p. 75 (Brisson MS.. in synonymy 
of Fuligula “Ray” [= Gray]) (type by virtue of substitution, Anas fuligula 
Linnaeus). 
Diagnosis —Similar to Fulir, but tip of bill much rounded, its width at 
posterior end of nail less than 21/2 times the length of nail: and head with 
a long occipital crest. 
Description——Wing 5 times the length of exposed culmen ; bill relatively 
little flattened terminally, its width near end 11/10-12/10 times its width 
at base, its tip rounded, its width at posterior end of nail 2-2 1/4 times the 
length of nail; tip of maxilla much hooked; nail of bill broadly triangular ; 
height of bill at extreme base 5/6-19/20 of its greatest width: base of cul- 
men not deeply concave; length of exposed culmen 2-23/8 times the height 
of bill at extreme base. 19/10-2 times the greatest width of bill, and decid- 
edly less than the length of inner toe with claw: anterior outline of feather- 
ing at the base of culmen triangular and acutely pointed; feathering on 
sides of maxilla not reaching forward as far as that at the base of culmen; 
a long (75 mm.). slender occipital crest. 
Type—Anas fuligula Linnaeus. 
Remarks —This bird is much more closely allied to the genus Nyroca 
than to Fulirc, despite its coloration, as may be seen from the diagnosis 
herewith given. Its long, pointed crest is unique among the species here 
considered, although some of the others have the feathers of the pileum 
lengthened into a short, bushy crest. 
The name to be applied to this genus is. of course, clearly Fuligula 
Stephens,’ as its type is, by tautonymy, Anas fuliguia Linnaeus. The name 
Platypus Brehm.? by some others cited in the synoniny of FPuligula, is a syn- 
onym of Somateria Leach, as is established by the designation of its 
type by Lesson* as Anas mollissima Linnaeus. 
The only species of this genus is Fuligula fuligula (Linnaeus).
