secondary quills and tall black. Feathers on sides of boJy beneath wings like the belly, but with white tips. 

 wing, 13.80 ; tarsus, 2.30 commissure, .1.50. 

 . Ilab. — Pacific coast of North America. Very rare on the Atlantic coast. 



Length, 29 inches ; 



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.

 resting only on very insufficient evidence.
