point; bill of female not very dissimilar, lacking the swelling at the base; color 
entirely black all over, without any white; bill black along the edges and tip; the 
swollen basal portion red to beyond the nostrils. 
Female. — Brown: lighter on sides of head, throat, and under surface of body, 
where the feathers have each an obscure dusky spot. 
Length, twenty-three and eighty one-hundredths inches; wing, nine and twenty 
one-hundredths; tarsus, one and seventy-eight one-hundredths; commissure, two 
and fourteen one-hundredths inches. 
This species is also known on the coast by the name of 
Coot. It is far less abundant than the other, but has all 
the habits of that bird. It also associates with it, and is a 
very expert diver; sinking beneath the surface of the water, 
at the flash of a gun, before the shot reaches it. I know 
nothing of its breeding habits, and have no eges by me for 
description. 
SOMATERIA, Lracu. 
Somateria, LEACH, in Fleming’s Philos. Zool. (1822). (Type Anas mollissima, L.) 
Bill much compressed, tapering to the tip; the nail enormously large, and forming 
the terminal portion of the bill, and much decurved; the feathers of forehead 
advancing forward in an acute long point, separating on each side a frontal exten- 
sion or linear process, or the feathers of the cheek may be said to extend a 
considerable distance along the commissural edge of the bill; nostrils situated 
anterior to the middle of the commissure; tail rather pointed, but short, of fourteen 
feathers.
