PERISTERA.—LEPTOPTILA. 257 
easily distinguished from P. cinerea by the broad white tips to the outer tail-feathers 
and by the maroon-coloured breast. 
A male brought tous at Calderas, Guatemala, on the 9th of October, 1873, by a 
hunter, Julian Medio, had the soft parts as follows :—* Tris reddish-orange ; bill black; 
tarsi and toes dull red; claws black.” 
Count Salvadori has pointed out that in the Mexican and Guatemalan birds the 
under wing-coverts are not cinnamon, but black. This we find to be the case, and as 
there is a gap in the geographical range of the species, it is possible that the Central- 
American form is distinct from that inhabiting South America; it must, however, be 
noted that we have not yet seen a specimen from Costa Rica. 
Subfam. GEOTRYGONINA. 
The Ground-Pigeons of this subfamily frequent forest-regions, and very much 
resemble Game-Birds in appearance. ‘The wings are rounded as in the Peristerin, but 
not to the same extent, the primaries being decidedly longer than the secondaries ; and 
they are without metallic spots or bands. The legs are very stout, and the tarsus 
is of considerable length, differing from that of the ordinary Pigeons and indicating 
the terrestrial habits of the group. 
The genera which Count Salvadori includes in the Geotrygonine are nine in number, 
of which two occur in Central America, viz. Leptoptiia and Geotrygon, the former with 
eleven out of nineteen known Species, and the latter with seven out of seventeen: both 
are, therefore, largely represented within our limits. Of the others, Haplopelia is 
peculiar to Africa, Osculatia to South America, Starnenas to Cuba and the Florida 
Keys, and Phlogenas, Leucosarcia, Eutrygon, and Otidiphaps to Australia. 
LEPTOPTILA. 
Leptoptila, Swainson, Class. Birds, ii. p. 349 (1837) ; Salvadori, Cat. Birds Brit. Mus. xxi. p. 543 
(1893). 
The members of this genus have the first primary attenuated at the tip, and the tail 
is more than half the length of the wing (cf. Salvadori, J. ¢.). 
The genus Leptoptila is somewhat largely represented in the Neotropical Region, 
and extends into the Southern United States. About twenty-five species are now 
recognized, but some of them are based on very slight differential characters.
