Sp. Ch. — Bill and legs black. General color carmine red, not continuous above, however, e.\cept on the head ; the feathers 

 showing brownish centres on the back, where, too, the red is darker. Loral region, base of lower jaw all round, sides and 

 posterior part of body, with under tail coverts, ashy, whitest behind . Wing with two white bands across the tips of the greater 

 and middle coverts ; the outer edges of the quills also white, broadest on the tertiaries. 



Female ashy, brownish above, tinged with greenish yellow beneath ; top of head, rump, and upper tail coverts, brownish 

 gamboge yellow . Wings as in tlie male. Length about 8.50 ; wing, 4.50 ; tail, 4.00. 



llab. — Arctic America. South to United States in severe winters. 



In comparing an American specimen of tlie Pine grosbeak (1208) with a European, (P. enu- 

 cleator,) in the collection of the Philadelphia Academy, I find the former considerably larger, 

 (wing 4.76, instead of 4.40,) the bill much stouter and more bulging at the sides, the tip of 

 the upper mandible much less decurved and less projecting over the lower. The tail feathers 

 are much broader. The legs are black, the bill dark brown, instead of both being horn color. 

 There is little difference in the character of the red ; there is, however, much more white on 

 the wing in very broad and sharply defined pure white external edgings of the quills, especially 

 on the tertials, secondaries, and greater coverts, instead of having these narrower, less conspicu- 

 ous, and tinged with rose. Without being sure that these differences of the two skins are either 

 constant or characteristic, I think it proper to quote such references only as belong to American 

 specimens.
