Third quill longest; 2d and 'tth scarcely lead; let intermediate between 5th and 6th. (No. 2,034.) Total length, ; wing, ; tail, ; width of outer feather, .30; difference of 1st and 3d primaries, .27, of 2d and 5th, .15, of 3d and 9th, .54; length of bill from forehead, .66, from nostril, .37, along gape, .77; tarsus, .70; middle toe and claw, .53; hind toe and claw, .44 (claw broken). The ashy cap does not extend over the nape, and is rounded off behind, leaving the sides of occiput olive. A specimen from Trinidad, belonging to Mr. A. Newton, differs in much brighter and deeper olive and yellow shades; the ash of cap extends farther back on the nape, but is rather rounded behind. The concealed portion of the tail feathers is almost as distinctly olive as the back. The wing is unusually long, measuring ; the first quill is about equal to the fifth ; the difference of shortest and longest quills .62. Another specimen (No. 8,050, from Guatemala), which may pos- sibly belong even to a different species, is equally bright in colora- tion with preceding, and the ash of cap extends still more over the nape, widening behind; the posterior outline almost transverse. The tail feathers are broader (.35); the wing shorter (); the first quill intermediate between the fifth and sixth ; the difference of longest and shortest quills .55. One from Ecuador, referred here, in poor condition, differs in some minor points. One from Buenos Ayres, again, is unusually large, the tail long
