When I compared two specimens of Nyctibius from Costa Rica with 

 a bird from Jamaica (which is typical N. Jamaicensis) I was surprised 

 to find them precisely alike in almost every character of any im- 

 portance. The wing and tail and general coloration were exactly the 

 same. The Jamaican bjrd had some slight tinge of rufous on the 

 back and on the abdomen, which was also present in one of the Costa 

 Rican birds, the other, however, being without it. The color-pattern 

 of the tail was the same, also the intensity of color. 



This great goatsucker is one of the very rare species of the family 

 found in Costa Rica, probably not more than a half-dozen speci- 

 mens ever having been taken in that country. It seems to be dis- 

 tributed over the whole of the country, specimens having been taken 

 on the Caribbean lowlands (Guapiles), the central plateau (Sarchi de 

 Alajuela), and the southwestern Pacific lowlands (El General de 

 Terraba). 



The specimen taken at Guapiles was caught alive in a banana plan- 

 tation by a laborer.

1 Chordeiles virginianus henryi. — I have been recently informed by Mr. C. H. 

 Lankester that he has in his collection a single skin collected at Miravalles, Costa 

 Rica, in 1906, which was identified by Mr. Ridgway as the Western Nighthawk. 

 This identification was made by Mr. Ridgway entirely from memory, with no 

 specimens to compare with, in which case there is some room for error. I have 

 not seen the bird and can only give the record as it thus stands. If it should prove 

 to be correct it adds another species to the list of Costa Rican birds.
