GEN. CHAR. Bill not much more than half the length of the head; gently

decurved from the base, notched at tip; commissure curved. Gonys

straight, or slightly concave. Rictal bristles quite well developed.

Wings rather shorter than the tail. First primary about equal to, or

rather more than, half the second; third, fourth, and fifth quills

nearly equal, sixth scarcely shorter. Tail considerably graduated; the

feathers stiff, rather narrow, especially the outer webs, lateral

feathers about three quarters of an inch the shorter in the type.

Tarsi longer than middle toe and claw by rather less than an

additional claw; tarsi conspicuously and strongly scutellate; broad

plates seven.

Of this genus there are many species in America, although but one

occurs within the limits of the United States.

The single North American species _M. polyglottus_ is ashy brown

above, white beneath; wings and tail black, the former much varied

with white.
