Genus Iolæma Gould

Generic characters.

Male.— Bill considerably longer than the head and slightly arched; wings long and curved; primaries rigid, of moderate length, and forked; tarsi clothed; feet rather small; hind toe shorter than the middle toe; nails short and curved.

This genus was proposed for the Trochilus Schreibersii of Loddiges; and of this form Mr. G. N. Lawrence, of New York, has made us acquainted with a second species in his Iolæma frontalis. Both these birds inhabit the eastern slopes of the Andes of Ecuador and forests bordering the River Napo.
