 inteiTupted on the throat, even in very dark-plumaged examples, but occasionally separated into 

 two patches by a black throat-stripe, as in Icumparna and occiiJcnlaUn, tlie plumage otherwise being 

 light colored. 



fi. leucopareia. — Little White-cheeked Goose. 



Adult (No. 62526, $ ad., St. Paul's Island, Alaska, May 14, 1872 ; II. W. Elliott) : Throat 

 with a black " isthmus " .75 of an inch broad, separating widely the white cheek-patches. A distinct 

 wliite collar between the black of the neck and dark brownish gray of the juguluni, tliis about .75 

 of an inch wiile in front, and extending completely around, though mucli narrower, and somewhat 

 interrupted, beliind. Lower parts dark brownish gray, abruptly detincd against the white of tlie 

 crissum. Wing, 14.25 inches ; culmen, 1.30 ; depth of maxilla at base, .75 ; width, .65 ; tarsus, 

 2.55 ; middle toe, 2.30. Tail feathers, 14. 



Other specimens in the collection are cliiefly in summer plumage, having paler lower parts and 

 less conspicuous white collar ; but nearly all have the two cheek-patclies completely separated by 

 a broad black isthmus on the throat. 



With only two exceptions, the specimens are from the Pacific coast, chiefly the northern 

 portion. 



No. 9956, North Red River (September ; R. Kennicott), is one of the smallest in the series, 

 and is otherwise peculiar. It is apparently a young bird, as its plumage presents some feauires 

 indicative of immaturity. The black of the neck fades gradually into the smoky gray of the jugu-
