than in that species.

This is a fairly well-marked form of the grey-chested Leptoptile, distinguished by 
its clear rufous nape. Nothing is known of its habits.

This is a very distinct species, belonging to the short-tailed group of the genus. 
GEOTRYGON. 
Geotrygon, Gosse, Birds of Jamaica, p. 316 (1847); Salvad. Cat. Birds Brit. Mus. 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. :
