BANGS AND PENARD: SURINAM BIRDS. 87 



Euphonia olivacea Desm. from Colombia to Cayenne, and from 

 central and western Brazil to northeastern Peru and Bolivia. 



We have compared a series of males from Surinam with two adult 

 males, one from the Upper Amazon (probably Rio Negro), collected 

 by Newton Dexter on the Nathaniel Thayer Expedition, and one 

 from Yquitos, Peru. The difference in coloration is sufficiently great 

 to warrant separation of the Upper Amazonian form as 



274a. Tanagra olivacea mellea subsp. nov. 



Type.— M. C. Z. E. A. & O. Bangs Coll. 23,020. Adult c^ . Yqui- 

 tos, Peru. Dr. Hahnel. Count von Berlepsch in exchange. 



Characters. — Similar to T. o. olivacea (Desm.), and of the same size, 

 but back much more purplish and less greenish, the purple of the head 

 not so sharply contrasting with the color of the rest of the upper parts. 

 The difference is somewhat similar, although not so marked, to that 

 shown by Tanagra violacea violacea (Linne) and Tanagra violacea 

 magna (Berl.). 



Measurements. — Type, adult cf ; wing, 50; tail, 25.5; tarsus, 12; 

 exposed culmen, 7.5.

Four specimens, both sexes. Vicinity of Paramaribo, February, 

 July, and December. 



276. Tanagrella velia velia (Linne). 

 One adult cf, Lelydorp, March. 



277. Tangara mexicana mexicana (Linne). 



Eleven specimens, both sexes. Vicinity of Paramaribo, and Javaweg, 

 February, March, April, May, and June. 



278. Thraupis episcopus episcopus (Linne). 



Eleven specimens, both sexes. Vicinity of Paramaribo, January, 

 February, March, April, May, June, and July.
