2? Cotyle flavigastra, ScuateR, P. Z. 8. 1857, 212 (Orizaba). 
Hab. Mexico and Guatemala. 
(No. 30,716, 4,.) Above smoky brown, almost inappreciably lighter on the 
rump, darker on the head; quills and tail feathers smoky brown, the secon- 
daries and greater coverts edged towards their ends with whitish. Chin and 
throat pale reddish fulvous, but in distinct contrast to the mouse gray of the 
breast, sides of body, and inside of wings. Rest of under parts white, with 
a faint trace of yellowish; the crissum pure white, the long feathers without 
brown tips, the shafts only faintly brownish towards the end. The feathers 
of axillars and inside of wings slightly edged with fulvous. 
In young birds the wing coverts and quills above are broadly margined 
with reddish fulvous ; the breast as well as the throat washed with the same. 
(No. 30,716, %.) Total length, 5.00; wing, 4.20; tail, 2.20, depth, .20; 
length of bill from forehead, .40, from nostril, .20, along gape, .55, width, .45 ; 
tarsus, .40 ; middle toe and claw, .55, claw alone, .19; hind toe and claw, .35, 
claw alone, .16. 
This species, originally established upon a young bird, appears 
perfectly distinct, and is intermediate in character between serri- 
pennis and ruficollis. The only adult I have seen is in autumnal 
plumage, and has a silky gloss that I have not noticed in spring speci- 
mens of serripennis (no autumnal ones being at hand for compari- 
son). The color of the upper parts, back as well as wings, appears to 
be decidedly darker. The differences of the under parts consist in
