Bill thicker and higher than even in Treron, but the rhamphotheca, though occupying more than two-thirds of the culmen, does not extend back to the feathers of the forehead. Sexes differing slightly, but there is no red on the back of the male. Sinuation of third primary less than in Crocopus, but still well marked. Tail rounded, lower tail-coverts extending to the ends of the outer rectrices. A single species.
