198 REVIEW OF AMERICAN BIRDS. [PART I. 
more restricted. A young bird with much worn plumage belonging to Dr. 
Gundlach’s collection, the same as that referred to by Mr. Lawrence, is ashy 
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 much 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 Ist quill not .16 less 
than the 2d; the 2d longest; the 3d and 4th successively very little 
shorter ; the Ist 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 Ist 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 
yéllow, instead of being of this color nearly to the shaft. As already
