﻿154 CASSIN'S DESCRIPTIONS OF NEW SPECIES OF PSITTACIDiE. 



and nearly equal ; quills broad, tail of twelve feathers, moderate, rather broad ; tarsi 

 short, robust; small space around the eye, bare. 



Dimensions. — Total length (of skin) from tip of bill to end of tail about 12 inches 

 Aving 8, tail 4£ inches. 



Color. — Top of the head from the base of the bill, fine crimson, varying in extent 

 in different specimens ; other plumage of the head above, green at the base of the 

 feathers, many of them having subterminal transverse bands of bluish cinerous, and 

 all narrowly tipped with black. Cheeks fine pale green, (with no yellow nor red.) 



Entire plumage above and below, green ; dark on the back and tinged with yellow 

 on the under parts ; every feather of the back, rump, neck, breast and abdomen nar- 

 rowly tipped or edged with black. First primary black, others green for the greater 

 part of their length, but bluish black at their tips. A large spot of fine crimson 

 occupying about the middle third of the first five or six secondaries, which are tipped 

 with fine blue. Tail above and below dark green at its base, terminal portion greenish 

 yellow, central feathers darkest, some of the outer feathers edged with reddish chest- 

 nut at their bases. Under tail coverts yellowish green, shafts of the feathers black. 

 Bill (in skin) pale yellowish. 



Hob. — South America. Brazil ? 



Obs. — Several specimens of this bird are in the collection of the Academy, variously 

 labelled, but mostly " Psittacus vernans?" and" Amazona lilacina. Less." It is not 

 the latter, and I do not know the former, if there is such a species. 



This species considerably resembles G. autumnalis, (Linn.) but is invariably smaller 

 and has no yellow markings on the face. The bill is clear yellowish white, with no 

 tinge of brown or horn color, as in that species. The extent of the space on the 

 head occupied by both the crimson and bluish ash colors, varies much in different 

 specimens, and in one the latter color is nearly invisible.
