FAMILY DIDIDAE. 



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. 



DIDUS LINN. 



SKULL with a very large and deeply hooked rostrum, and the nasal and 

 maxillary processes of the praemaxilla converging anteriorly ; the front 

 region inflated into a sub-conical prominence of cancellous tissue. Neck 

 and feet shorter than in the succeeding genus. Delto-pectoral crest of 

 humerus distinct. 



Two species : Didus cucullatus and Didus solitarius.
