I am indebted for this new bird to Miss E. Yeates, who received it with a few others from some part of Brazil: it seems to connect the genera of Ampelis and Procnias, having the bill much less dilated at the base than any of the latter; it however has a close similitude to Procnias melanocephalus ([Pl. 25.]), which seems further removed from the true Chatterers.
Total length eight inches and three quarters. Bill in extreme length near an inch; the colour dark cinereous; the base furnished with bristles something resembling the Chatterers: the opening of the nostrils large, round, terminal, and nearly naked; the feathers on the crown lengthened; the whole head, neck, and fore-part of the breast black, bordered above by a narrow collar of yellow; back and scapulars brown, rump olive; sides of the breast, inner covers, and under parts uniform yellow; wing-covers black margined with olive, those on the shoulders tipt with brown, the rest with yellow; quills and tail black margined with olive. Wings four inches and three-quarters long, the first quill very short, the third longer than the second. Tail four inches long.
