copariea. Large space on the throat and sides of the head white, head above 
and neck black, back and wings ashy brown, with the feathers having paler tips 
and edges, rump and tail black, upper tail coverts white; plumage beneath ashy 
white with a silky yellowish tinge, and many feathers having darker subterminal

Hab. Vera Cruz, Mexico. | 
Obs. One specimen of this singular bird has been several years in the collec- 
tion of the Academy, having been presented by its eminent member Marma- 
duke Burrough, M. D., and, collected by him during his residence at Vera Cruz. 
It resembles the common Avser canadensis in general appearance, but may at 
once be distinguished by the smaller size of the tarsi and feet, as well as its 
comparatively small and weaker bill. It is much larger than either Bernicla 
Hutchinsit or Bernicla leucopariea, both of which are in the collection of the 
Academy. 
The Committee to which was referred Mr. Cassin’s “ Catalogue of the 
Halcyonide in the collection of the Academy,” reported in favor of 
publication. (#@ See end of the present No.)
