Includes very large and massively-built forms, agreeing with the
_Columbidae_ in the truncation of the angle of the mandible, but with the
extremity of the cranial rostrum strongly hooked. They were totally
incapable of flight, the wing-bones being small, the carina of the sternum
aborted, and the caracoidal grooves shallow and separated from one another.
Two genera: _Didus_ and _Pezophaps_.
