This is a very distinct species, belonging to the short-tailed group of the genus. 



GEOTRYGOX. 



Geotrygon, Gosse, Birds of Jamaica, p. 316 (1847) ; Salvad. Cat. Birds Brit. :Mu8. xxi p 564 

 (1893). 



This genus differs from Leptoptila in not having the first primary attenuated at the 

 tip. All the species are very Galline in appearance, resembling Partridges. The 

 tarsus in the species of Geotrygon is covered with transverse scales in front, and 

 the rather short tail consists of twelve feathers. 



Of the eighteen species enumerated by Count Salvadori, six are confined to Central 

 America, and a seventh, G. montana, is of wide distribution throughout the Neotropical 

 Region. The others are either strictly South American, or else confined to the West- 

 Indian Islands.
