Genus Gerygone, Gould.
Generic characters.
Bill shorter than the head, swollen, notched at the tip; commissure straight; nostrils basal, lateral, oval; rictus beset with two or three extremely fine and weak bristles; wings moderately long, first quill almost spurious, second long, third, fourth and fifth equal and longest; tail rather short and square; tarsi entire, slender, moderately long; toes extremely short and small, the lateral toes even, and united to the middle one nearly to the first joint; claws much curved.
The term Psilopus was originally proposed by me for this genus, but that name having been previously employed, Gerygone was substituted for it.
A group inhabiting every part of Australia, and probably New Guinea and Polynesia. Their chief food consists of insects of the most diminutive size, such as aphides, gnats and mosquitos. The more thickly-billed species may probably feed upon larger insects and their larvæ. They mostly frequent the thick umbrageous woods, where they dart about for insects under the canopy of the dense foliage, or sally forth into the open glade like true Flycatchers. Their nests are of a domed form, with the entrance near the top, some species protecting the opening by constructing a projection above it like the eaves of a house; the eggs are generally four in number, and spotted with red like those of the Maluri and Pari.
