392 CAPRIMULGIDZ. 
Mr. Lloyd shot our bird on 11th May, 1889, at an elevation of 8000 feet above the 
sea in the mountains of Jalisco. We may therefore infer that this species is a 
mountain-bird and has a range extending from the Sierra Madre of Chihuahua to 
that of Jalisco. | 
In the width and shape of the white patches on the outer rectrices Otophanes 
resembles Caprimulgus yucatanicus and C. ocellatus, a fact which may prove of 
significance when we know more about these birds. 
STENOPSIS. 
Stenopsis, Cassin, Pr. Ac. Phil. 1851, p. 179; Hartert, Cat. Birds Brit. Mus. xvi. p. 582. 
Stenopsis is closely allied to Caprimulgus, but has a squarer even emarginate tail, a 
character which is more evident in the type S. cayennensis than in the other species of 
the genus. The bill is more elongated in comparison with its breadth, the nostrils 
more exposed, the first primary is nearly equal to the second, the tarsi are feathered 
along the front for about one third of their proximal ends; the sexes differ in colour, 
especially as regards the pattern of the outer rectrices and the outer primaries. 
The genus contains five species, which are spread over the greater part of South 
America, even as far south as Northern Patagonia. Only one species, S. cayennensis, 
enters our fauna as far as Costa Rica; but S. ruficerviv is found in the Colombian 
State of Antioquia, just beyond our southern boundary.
