Though this Goatsucker has a close general resemblance to C. carolinensis, so much 
so that our only Central-American specimen was at first referred to that species’, the 
two birds are in fact very distinct. The present species may at once be distinguished 
from its ally by the structure of the long strong rictal bristles; the shafts of these 
are bare and not furnished with the fine lateral filaments found in C. carolinensis, and 
in it alone of the American Caprimulgide. C. rufus therefore, in this respect, resembles 
the rest of the family. 
The range of this Goatsucker is very extensive and includes a large portion of 
tropical South America. Its southern range includes the Brazilian province of Rio 
Janeiro and its northern the West-Indian Island of Santa Lucia and Chiriqui within 
our limits: from the latter country a single male specimen was sent us by our 
collector E. Arcé in 187047; it was accompanied with a male of C. carolinensis.
