1158 MR. C. E. HELLMAYR ON THE 



The Tring Museum possesses an adult male obtained by 

 Mr. Rosenberg at Rio Dagua (Juntas), Ma,y 27, 1895. The males 

 from W. Colombia agree, in coloration and size, with a series from 

 Western Ecuador and Chiriqui, the under tail-coverts being 

 black with distinct white apical margins. 



T. m. transandeanus is, otherwise, known only as an inhabitant 

 of the lowlands (from sea-level up to 1000 feet), and its occurrence 

 at La Selva (4600 feet alt.) must be regarded as exceptional. 



In the Central and Eastern Cordilleras it is replaced by a nearly 

 allied, but easily recognizable race, T. m. granadensis Cab. *, 

 which forms the passage to T. m. melanurus Gould, of Upper 

 Amazonia. It differs, in the male sex, from T. m. transandeanus 

 in having the under tail-coverts cinereous with a white apical 

 edge preceded by a distinct blackish subterminal band, and in 

 its much slenderer, weaker bill. I have examined several Bogota 

 skins in the collections of the Paris and Munich Museums, an 

 adult male from Antioquia (Salmon) f, and one from near 

 Merida (Briceno) at Paris, and four males from N.W. Venezuela 

 ( cJ ad., S imm., Mt. Bucarito, Tocuyo ; J ad. Ejido, near 

 Merida ; cJ ad. San Esteban — Mocquerys coll.) in the Tring 

 Museum. All of them very clearly show the characters indicated 

 above. Cfr. also Menegaux & Hellmayr, Bull. Soc. Philom.
