This species is very distinct from any of the others noticed above, by reason of its 
white throat and dark leaden-grey under surface, the feathers being centred with 
broad black shaft-streaks. 
We have no information at present as to its habits.

Callipepla, Wag). Isis, 1832, pp. 277, 1229; Grant, Cat. Birds Brit. Mus. xxn. p. 394 (1893). 
The single species of this genus may be distinguished by the colour of the sexes 
being almost similar, and by the short crest, which does not extend much beyond the 
feathers of the head. ‘The tail is about three-fourths of the length of the wing and is 
composed of fourteen feathers.
