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 back ; 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. maculatus' of Eecua- 
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). 
T 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. Tileman, Rio Potochic, Guatemala, Jan. 1861.) It does 
! A specimen of Malacocichla, in Mr. Lawrence’s collection, from the Napo, 
with a general resemblance to a type Napo skin of /. 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).
