1 98 REVIEW OP AMERICAN BIRDS. [PART I. 



more restricted. A young bird with much woru plumage belonging to Dr. 

 Gundlaoh's collection, the same as that referred to by Mr. Lawrence, is asliy 

 above, with patches of olive-green ; the under parts creamy white, strongly 

 tinged with yellow across the breast and on crissum. The yellow patches 

 of tail feathers mucli restricted. A young male (34,504), farther advanced, 

 has the adult plumage, with only a few patches of light ashy on the nape and 

 sides of neck, and some whitish spots on the chin. 



Length of 34,504, ^,4.90; wing, 2.50; tail, 2.20; tarsus, .88; bill from 

 nostril, .32. 



For the opportunity of examining specimens of this species I am 

 indebted to Dr. J. Gundlach, who has transmitted five specimens of 

 different ages and sexes. None of these, however, appear to be in 

 highest spring plumage, for which reason the comparison with the 

 allied species cannot be made entirely satisfactory, and the differ- 

 ences in coloration may not be really quite as great as they now 

 appear. The difference in the structure of the wing would, however, 

 alone be sufficient to separate this species from petechia. The tips 

 of the outer four quills are closer together ; the 1st quill not .10 less 

 than the 2d ; the 2d longest ; the 3d and 4th successively very little 

 shorter ; the 1st longer, however, than the 5th. In petechia the 1st 

 quill is .20 shorter than the 3d (which is longest) ; the 4th is nearly 

 as long, and decidedly exceeding the 2d ; the 1st shorter than the 

 5th, or about equal to the 6th. 



None of the Cuban specimens before me show the red vertex of 

 the full plumaged petechia of Jamaica ; the feathers being tinged 

 centrally like immature males of the latter species ; but, from Mr. 

 Lawrence's statement, the reddish crown belongs equally to both 

 species. The differences in wings and tail, however, exist throughout 

 the entire series of the species. The colors above are much brighter 

 and more yellowish in petechia; the wing coverts are broadly edged 

 with yellowish-green, like the back, which color on the edges, and 

 still more on the ends of the greater and middle coverts, passes into 

 almost decided yellow ; the edge of the alula and of the wing are 

 bright golden yellow ; all the quills are edged conspicuously and 

 uniformly on the outside like the back, and inside abruptly with 

 yellow. In albicollis the edging of the wing feathers is much duller 

 and more uniform, without the bright yellow of the coverts and alula. 

 The outer edges of the primaries are more inclined to gray ; the 

 yellow of the inner edges of the quills paler, and less abrupt. The 

 yellow of the inner webs of the tail feathers in albicollis is more 

 contracted ; does not come up so sharply to the shaft, but is usually, 

 separated from it, and the 5th feather has only the inner margin 

 yellow, instead of being of this color nearly to the shaft. As already
