226 REVIEW OF AMERICAN BIRDS. [PART if 
from nostril, .385; greatest depth, .185 ; tarsus, .91; middle toe and claw, .80; 
hind toe and claw, .60. 
The species above described, if its characters are maintained 
throughout a series of specimens, appears to me worthy of separation 
from velata and equinoctialis, being really more different from them 
than are the two latter from each other. Whether the two speci- 
mens are identical as species remains to be proved; the difference 
between the white eyelids of the one, with the eye not encircled be- 
hind by black, and the narrow black border behind the eye of the 
other, to the exclusion of the white eyelids, is somewhat analogous 
Q to that distinguishing G. macgillivrayt from G. philadelphia. The 
former condition may, however, be only a feature of immaturity, as 
: the female and young G. philadelphia have whitish eyelids. 
S The differences from allied species are expressed in the synopsis.

: The ash of the head is even more extended than in G. velata—reach- 
ing over the nape and on the sides of head, where it replaces much 
re of the black of the cheeks of the others. The bill is much stouter, 
oy the culmen more curved ; the tail is longer, and the wings shorter and 
more rounded. The legs are apparently intermediate in character.
