Spermophila corvina is a bird of Eastern Mexico, being found in the State of Vera 
Cruz§ and at Playa Vicente, whence the types came!. In Guatemala and Honduras, 
too, it is a bird of the eastern forests, as is also the case in Costa Rica. In Nicaragua 
alone it approaches the Pacific, having been found at Los Sabalos on the western 
shore of the Lake of Nicaragua, still, however, on the eastern side of the Cordillera. 
It is a bird of the lowlands, and is usually found in clearings of the forest feeding on 
small seeds, especially those of grasses.

Hab. Panama, Bugaba (Arcé*), Lion Hill (/‘Leannan®’).—Cotomsia?; VENEZUELA 5 
and TRINIDAD 2; GUIANA 2. 
My. Sclater seems to us to have rightly united the Panama with the Guiana bird of 
this form, and with them placed all coming from intermediate localities under the name 
Spermophila grisea, that given by Gmelin to D’Aubenton’s “ Gros bec de Virginie” }, 
which evidently refers to the same bird. 
Both Mr. Sclater and Mr. Lawrence allude to the white spots on the side of the 
neck of many Panama birds, and also to their variable character. We have a 
specimen from Chiriqui with no spots at all, and another where they are plainly 
shown, so that they do not serve to distinguish Panama from more southern and 
eastern birds. 
The occurrence of §S. grisea in Guiana has been recorded by Mr. Sclater?.
