$ : Upper parts ashy, more or less olivaceous, changing to greenish on 

 the nape. Head and neck all around orange-brown or intense saffron-yellow, 

 with a broad black bar on the side of the head through the eyes. Wings 

 blackish, the inner webs of all the quills edged with white, the outer webs 

 of most of the primaries with whitish, and the outer webs of the secondaries 

 with greenish ; most of the primaries also marked with white on the outer 

 webs at base, forming a conspicuous spot (only seen elsewhere in D. ccerules- 

 cens, which is altogether different in other characters). Tail like the wings, 

 with greenish edging of most of the feathers, the two outer ones on each 

 side mostly or wholly white. Belly and sides whitish, tinged with olive or 

 brownish. Length, about 4f ; wing, 3.00 ; tail, 2-2 ; bill, ^ ; tarsus, f . 



The female is described as having the saffron color much clearer yellowish, 

 and shaded with olive-green on the crown ; the black bar replaced by whit- 

 ish, excepting a dusky patch on the auriculars. The very young bird does 

 not appear to be known. 



THE present is one of the " sixteen species 77 described and

 to the ascribed habitat of these birds, the presumption being 

 that some, if not all, of them actually came from contiguous 

 Mexican territory. But it is well to bear in mind that their 

 describees declaration of their origin was unwavering to the 

 last, and that his statement is gradually being borne out by the 

 rediscovery of his species within our limits; while the Texan
