Adhesion of toes as in HylophUvs vtridifaims. Lawk. (Panama.) This genus is easily distinguished from the Vireos by the conical, more acute bill, but slightly decurved at tip, more arched com- missure, longer hind toe, much larger claws, and a more rounded wing than usual in Vireo. In the character of the feet it comes quite near Laletes. The species of HylopMlus which I have had the opportunity of examining agree very well in general characters, the principal varia^ tion consisting in trifling differences in the proportions of the quills and length and graduation of tail. The first quill is- usually less than half the longest: in insularis it is more than half. The tail in the type is longer than the wing; in others it is about equal; in a few species it is shorter. The following synopsis expresses the characters of the species known to me :— Common Chaeacters.—General color of upper parts olive green, the head, or at least the forehead, usually differing in having an ochrey or rufous wash, sometimes seen on the tail or back, sometimes wanting ; the forehead gener- ally more yellowish. No bands on wings or tail. Under parts whitish, yellowish, or olivaceous. Bill generally pale. Legs flesh color or plumbeousi. A. Head and nape above uniform cinnamon brown. Fore- head not different. Rufous of hea
