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

 bia. The Antioquian form east of the Western Andes is doubtless J/, c. 

 magdalenw. Hellmayr (/. c.) has called attention to the obvious error in 

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

 said to ha^•e 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.
