dered with a membrane, have a larger head, a shorter neck, the 
“feet placed farther back, smaller wings, a stiffer tail, more com- 
pressed tarsi, longer toes, and the membrane of the feet more entire. . 
They walk with more difficulty, feed more exclusively on fish and 
insects, and dive more frequently.(1) Among them we may distin- 
guish the 
Omen, Fleming. 
By the breadth and inflation of the bill. 
Anas nigra, L.; La Macreuse commune, Enl. 972; Naum. 
Supp. 14, f. 28 and 29; Brit. Zool. pl. 2, 6; Wils. VIII, Ixxii, 
2.(The Scoter), is all black, greyish when young; the bill 
very broad with a protuberance on its base. It is found in 
large flocks on the coast of France, where it feeds chiefly on 
muscles. The An. cineraceus, Naum., I; C. 60, f. 91, 92, is. the 
young female. 
An. fusca, L.; La’ double Macreuse, Enl. 9563; Frisch, 165; 
~ Naum. I, c. Supp. f. 15 and 16; Wils. LXXII, 3 (The Velvet 
Duck); differs in its superior size, a white spot on the wing, 
and a white streak under the eye. There is a circular, vertically 
flattened inflation in the middle of its trachea. 
An. perspicillata, L.; Enl. 995; Edw. 1553; Wils. VIII, Ixvii, 
1. (The Black Duck.) Some white on the occiput and behind 
the neck; the naked and yellow skin of the base of its bill also 
surrounds the eyes. 
New Holland produces a speckled species, remarkable for a 
large fleshy appendage that hangs under its bill, dn. lobata, 
Nat. Misc., VIII, pl. 255, and Col. 406.(2) , 
We may also separate 
Cuancuta, Leach. 
» In which the bill is short and narrower towards the end; and 
place first on the list, those species the middle quills of whose tail 
are the longest, which renders it pointed. Such are 
An. glacialis, L., Enl. 1008; Edw. 280; Naum. 52, f. 76; Wils. 
VIII, Ixx, 1, 2; the young male, Enl. 999; Naum. 52, f. 76, B; the 
adult in wedding livery, Edw. 156. (The Long-tailed Duck.)
