IX. — Descrijition of a supposed neio Species of Pigeon. 

 By JOHN Gould, F.R.S. 



Genus Otidiphaps, Gould. 



Size large, equalling that of a wood-pigeon, Columba oenas ; 

 hill longer than the head, straight, and plover-like ; wings 

 short and round, armed with a spur at the shoulder ; tail 

 round and moderately long ; tarsi very long for a pigeon, and 

 with the toes covered Avith thick plate-like scales ; nails some- 

 what straight and pointed ; general structure adapted for the 

 ground rather than for trees or for flight. 



Otidiphaps nobilis, Gould. 



Bill red or fleshy red, particularly on its basal portion; round 

 the eye a bare space, Avhich a])pears to have been of the same 

 colour; crown of the head and occipital crest black, with steel- 

 blue reflections ; back of the neck resplendent glaucous green ;
