350 REVIEW OF AMERICAN BIRDS. [PART I. 
ternally, and the longer ones internally with white, the latter edged externally 
with light ash. Bill and legs dark plumbeous. ‘‘Iris hazel.’’ Tail feathers 
narrowly edged all round with white, narrowest internally, and increasing 
from central to lateral feathers. Upper tail coverts clear ash. 
As the specimen in finest plumage (described above) is moulting the quills, 
the measurements are taken from another (37,010). In this the 1st quill is 
not quite one-third the 2d, which equals the 6th; the 3d and 4th longest. 
(No. 37,010.) Fresh specimen: Total length, 6.10; expanse of wings, 10.80, 
Prepared specimen: Total length, 5.75 ; wing, 3.25; tail, 2.70; difference be- 
tween 10th and longest quill, .95 ; exposed portion of 1st primary, .75, of 2d, 
2.34, of longest, 3d (measured from exposed base of lst primary), 2.54; 
length of bill from forehead, .55, from nostril, .31, along gape, .70; tarsus, 
-75; middle toe and claw, .60, claw alone, .21; hind toe and claw, .50, claw 
alone, .23. 
This species is in general character very similar to V. solitaria, 
although larger, especially with longer wings and tail, as shown by 
a comparison of the table of measurements. The olive green of 
solitarius is replaced by plumbeous, and the yellowish by white, 
forming a marked contrast in appearance. Only a faint trace of 
olive on the lower back and flanks represents the predominant colo- 
ration of solitaria. The olive external marginings of the wings 
are here replaced by ash; of the tail, by whitish. In some specimens, 
however, there is a slight edging of olive towards the base of the 
secondaries. 
The specimens described above were killed in August; others 
killed in May are quite similar. No. 29,359, from Colima, in Feb- 
ruary, is slightly more olivaceous on the lower back and flanks.
