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 is closely allied to Caprimulffus, 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 difier 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 Eica ; but S. ruficervix is found in the Colombian 

 State of Antioquia, just beyond our southern boundary.
