secondary quills and tail black. Feathers on sides of body beneath wings like the belly, but with white tips. Length, 29 inches ; 
wing, 13.80; tarsus, 2.30 commissure, 1.50. 
Hab. — Pacific coast of North America. Very rare on the Atlantic coast. 
This species, with a general resemblance to the brant goose, is yet very distinctly marked. 
The bill, though of the same length, is much wider. There is no conspicuous distinction 
between the black of neck and jugulum and the dark plumbeous brown of belly and back, the 
feathers of which have no lighter edges, but are perfectly uniform. The white patches on the 
sides of the neck are confluent below, not separated.

Bernicla leucopsis, ? 
Sp. Ch. — Forehead, cheeks, and under parts of the head white; the side of bill narrowly bordered with black. Crown, nape, 
lower part of neck, jugulum, fore part of back, rump, and tail black. Feathers of interscapulars and wings silvery bluish gray, 
passing into black towards the end, but with the extreme tip whitish gray. Nostrils similarly marked, but without the pale tips. 
Under parts uniform bluish white, the feathers on the sides only showing a darker basal portion. Upper tail coverts and sides of 
the tail at the base white. Bill and legs black. Length, 28 ; wing, 17 ; tarsus, 2.76 ; commissure, 1.40. 
Hab. — Europe. Very doubtful as an inhabitant of North America. 
Although this species is abundant in Europe, its occurrence in North America is very doubtful, 
resting only on very insufficient evidence.
