Adult male. General colour above light ashy brown, slightly 

 streaked with dark brown mesial lines on the dorsal plumage, which 

 is slightly tinged with rosy ; rump with a patch of deep crimson ; 

 lesser wing-coverts brown ; median and greater coverts dark brown, 

 edged with ashy brown, whitish at the ends ; bastard -wing, primary- 

 coverts, and quills dark brown, margined with ashy brown, whitish 

 on the edges of the primaries ; upper tail-coverts brown, tinged with 

 rosy and centred with darker brown ; tail-feathers brown, edged 

 with whity brown ; crown of head brown, very slightly washed 

 with crimson ; the forehead and sides of crown bright crimson, 

 forming an eyebrow ; lores and nasal plumes ashy white ; feathers 

 round eye and ear-coverts brown, with a crimson tinge ; fore part of 

 face, cheeks, throat, and breast bright crimson ; the abdomen, sides 

 of body, and flanks white, with a slight rosy tinge, all streaked with 

 dusky brown ; thighs ashy ; under tail-coverts isabelline, broadly 

 streaked with dark brown in the centre ; under wing-coverts and 

 axillaries dull reddish, those near the edge of the wing mottled with 

 dusky centres ; quills below dusky, ashy along the inner web. 

 Total length 5-2 inches, culmen 0-4, wing 3-1, tail 2-25, tarsus 0-65. 



Adult female. Scarcely to be distinguished from the female of 

 C. mexicanus, but rather paler brown above, decidedly lighter below, 

 the dark brown streaks less pronounced. Total length 5 - 6 inches, 

 culmen 0'4, wing 3, tail 2-3, tarsus 0-6. 



The transition in a series from C. frontalis to C. rhodocolpus seems 

 to me to be absolute, and I see no possibility of separating the two 

 forms, even as races. C. mexicanus perhaps merges into C. frontalis ; 

 but I have seen no sign of this in the series of specimens examined.
