Ramphoccenus rufiventris Scl. & Salv., P. Z. S., 1879, p. 525 (Sta. Elena). 



Char, subsp. — Similar to Ramphoccenus rufiventris rufiventris Bp., but with the 

 back slaty smoke-gray, the head less rufous gray, slightly tinged with cinnamon, 

 which is stronger, more ochraoeous on the forehead; sides of the head less strongly 

 ochraceous-buff; but ochraceous-buff of underparts, particularly of abdomen, 

 deeper. 



Known only from the northern end of the Western Andes, and Sub- 

 tropical Zone of the Central Andes.

Probably restricted to the Tropical Zone of the Pacific coast of Colom- 

 bia. The Antioquian form east of the Western Andes is doubtless M. c. 

 magdalencB. Hellmayr (l. c.) has called attention to the obvious error in 

 the alleged type-locality. It is probable that Pasto, whence the type is 

 said to have come, is, in a limited way, the 'Bogota' of southern Colombia. 

 In other words, as the commercial center of that part of Colombia, it is the 

 shipping point for the products of the surrounding country. Consequently 

 the specimens recorded below from Barbacoas on the trail from the coast 

 to Pasto, may doubtless be considered as topotypical.
