apparently an immature male, having the middle wing-coverts and 

 middle rectrices tipped with buffy. The tail-pattern is like that of the 

 adult male, except that the white is more restricted ; otherwise the 

 plumage is like that of the adult female. 



This magnificent trogon is a Subtropical Zone species, confined to 

 the heavy forest between the altitudes of 5,000 and 8,000 feet, and is a 

 rare bird. During the ripening season of the coffee the birds gather 

 along the edges of the upper part of the hacienda Cincinnati (5,000 

 to 5,500 feet) and feed on the ripe coffee berries. A nest was noted 

 at this point, built in an old cavity made by Scapaneus melanolcucos 

 malherbii in the top of an old dead stub of a tree, about fifteen feet 

 from the ground. Unfortunately the writer was unable to return to 

 investigate it further. 



It was thought at first that this species was peculiar to the Santa 

 Marta region, but we now know that it occurs in northern Venezuela 

 also, from which country the Carnegie Museum has several specimens.

These agree substantially with authentic specimens from Trinidad 

 and Cayenne, both in size and color. C. s. fumosa, of which we have 

 six specimens from Costa Rica, differs from spinicauda in its larger 

 size, brighter, blacker coloration, and darker gray rump-patch. It is 

 clearly conspecific with spinicauda, but not with cinercivcntris, as given 

 by Mr. Ridgway. Dr. Chapman (Bulletin American Museum of Nat- 

 ural History, XXXVI, 1917, 277) speaks of specimens from western 

 Colombia as being larger, whereas his measurements show them to be 

 the reverse, and to agree with the Las Vegas skins here recorded. 



This swift, like its larger cousin Strcptoprocne zonaris albicincta, 

 is here today and gone tomorrow, perhaps feeding over the San 

 Lorenzo in the morning; and over the Snow Peaks of the Sierra
