black show conspicuously; the tail is composed of rather narrow feathers, the outer 
ones being about half as long as the central pair; the upper tail-coverts are long and 
narrow, and reach to within an inch of the tip of the tail. The general colour of the 
plumage is tawny with dark centres to the feathers; the head has a tolerably 
conspicuous crest. 
The range of the only species is fully given below.

Diplopterus nevius is found sparingly but regularly distributed over a very wide area, 
extending from the middle of the State of Vera Cruz throughout Central America, and 
thence southwards over nearly the whole of the continent of South America as far as 
the southern provinces of Brazil. Its range in altitude is considerable, for, though 
chiefly a bird of the low hot districts, we found it as high as the neighbourhood of 
Duefas—that is, nearly 5000 feet above sea-level.
