LEPTOPTILA. 263 
L. cassini and its allies constitute the short-tailed group of the genus Leptoptila 
with a vinous-grey breast. This species was first described from the Rio Truando, and 
has been since found in the State of Panama, Costa Rica, and Nicaragua. M. Boucard? 
procured specimens in the valley of San Carlos at an altitude of 5000 feet, and found 
the bird nesting there in small trees, the male performing the duties of incubation. On 
the Volcano of Miravalles it was observed in numbers by Mr. Underwood, and is deseribed 
as a ground- and forest-loving bird. The eggs are white and two in number.

This form, as Count Salvadori has pointed out, is intermediate between L. cassini 
and L. cerviniventris. The chest is of a lighter grey, and the vinaceous colour of 
the breast is paler and tinged with grey. One of Mr. Richardson’s: birds from 
Chontales was compared by Count Salvadori with the type, and we have another since 
received from the Rio Coco; the latter is darker and closely resembles a Miravalles 
specimen of Z. cassini. 
The habits of this species are doubtless similar to those of other members of the 
genus Leptoptila.

This is merely a race of L. cassini, very difficult to distinguish from that species and 
L. vinaceiventris, as the latter is intermediate. The grey on the hind part of the neck, 
so distinct in L. cassini, is here almust wanting, the grey shade on the throat and front
