REVIEW OF AMERICAN BIRDS. 



[part I. 



more rufous. There are no streaks on the throat as in occidentalis, 

 or else they are very faintly indicated ; and the plumbeous of the 

 under parts is much darker than in melpomene. The bill and feet 

 are colored as in occidentalis, the feet still darker than in the latter 

 species. The bill is proportionally as large as in melpomene ; the 

 bristles apparently very long.

Above slaty olive-green ; the top and sides of the head, including 

 lower jaw, continuous and deep black ; beneath light ochry yellow, 

 becoming yellowish-white on the belly and anal region ; crissum 

 tinged with brown ; sides of body and inside of wings somewhat like 

 the Jback ; small indistinct spots of olivaceous on the chin and throat, 

 which become larger and more rounded on jugulum and breast. Bill 

 and legs yellow. 



Length, 6.00 ; wing, 3.60 ; 1st primary, .96 ; tail, 2.75 ; bill from 

 nostril, .40, from gape, .92 ; tarsus, 1.40; middle toe and claw, .96. 



This species is easily distinguished from C. maculahis^ of Ecua- 

 dor, by the much more olive back (not dark ash) and ochry yellow 

 breast. The wings are longer and the tail shorter in proportion (in 

 maculatus measuring respectively 3.50 and 3.00). 



I am indebted to Mr. Salvin for the opportunity of examining his 

 cabinet specimen of this species, lent me for the purpose. (No. 31, 

 Salvin coll. Tileraan, Rio Potochic, Guatemala, Jan. 1861.) It does 



' A specimen of Malacocichla, iu Mr. Lawrence's collection, from the Napo, 

 ■with a general resemblance to a type Napo skin of M. maculatus received from 

 Mr. Verreaux, is in some respects more like M. dryas. Thus the upper parts, 

 instead of being grayish sooty, are more olive, the under parts more ochrace- 

 ous yellow. The crissum, however, instead of being yellowish-white, like the 

 anal region, is of a snuffy brown. The tail is much longer (3.30).
