Length, 230 to 280 mm.; sexes alike in color; colors nearly uniform brown of various shades; a wide iridescent band on neck; primaries neither scooped nor cut; rectrices graduated and rounded and with gray tips; under tail-coverts gray or dark buff. Birds of this genus are closely related inter se, maculipectus alone showing a slight departure from the type in its mottled breast. The species fall naturally into two groups which might take the rank of subgenera were anything to be gained thereby. The first five species (see key to species), the amethystina group are rare deep-woods birds; their colors are generally darker brown than those of the leucotis group and the bill is noticeably longer and heavier, being longer than tarsus. The five species of the leucotis group are fairly common in their respective ranges; they are to be found in more open country or even on the borders of rice-fields; in this group the tarsus equals, or is slightly greater than, the culmen.
