This small goatsucker was first reported from Panama by Salvin 

 (Proc. Zool. Soc. London, 1870, p. 204) from a pair received from 

 Arce. The skins, in the Salvin-Godman collection in the British 

 Museum, are labeled "Chitra, Veragua" taken in 1868. Through 

 error Salvin listed them as from "Calovevora," a mistake copied 

 later by Salvin and Godman (Biol. Centr.-Amer., Aves, vol. 2, 

 1894, pp. 392-393). One in the American Museum of Natural His- 

 tory was taken at Frances, Chiriqui, October 26, 1905, by H. J.
