Hah. Costa Eica, Azahar de Cartago \ Alajuela, Estrella, and La Palma de San Jose 

 {Underwood, in litt.). 



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. 



Callipepla, Wagl. Isis, 1832, pp. 277, 1229; Grant, Cat. Birds Brit. Mus. xxii. 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.
