[PAltT I. from nostril, .35 ; greatest depth, .185 ; tarsus, .91; middle toe and claw, .80; hind toe and olaw, .60. The species above described, if its characters are maintained throughout a series of specimens, appears to me worthy of separation from velata and sequinoctialis, being really more different from tiicm 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 tlio other, to the exclusion of the white eyelids, is somewhat analogous to that distinguishing O. macgillivrayi from G. Philadelphia. The former condition may, however, be only a feature of immaturity, as the female and young O. Philadelphia have whitish eyelids. The differences from allied species are expressed in the synopsis. The ash of the head is even more extended than in G. velataâreach- ing over the nape and on the sides of head, where it replaces much of the black of the cheeks of the others. The bill is much stouter, the culmen more curved ; the tail is longer, and the wings shorter anJ more rounded. The legs are apparently intermediate in character.
