Ceriocleptes gen. nov. (Indicatoridæ).
Resembling Indicator in its bill and general form, save for the tail, which is composed of 12 quills, the two middle pairs of nearly equal length, somewhat pointed and curved strongly outwards, the next pair considerably shorter, but also pointed and slightly curved; while the fourth, fifth and sixth are straight, greatly narrowed, and stiffened, becoming successively shorter, so that the outermost pair is not half so long as the median. The tail-coverts are unusually long, those below as long as the longest rectrices, and projecting in the fork of the tail.
