Hellmayr (Nov. Zool., XIV, 1907, 7), it is true, disallows the differences, 

 but his material was very scanty.

Tangara cayana fulvescens, subsp. nov. 



Similar to Tangara cayana cayana (Linnaeus) of Guiana, etc., but larger, 

 and decidedly paler throughout. Wing (type), 75; tail, 54; bill, 11.5; 

 tarsus, 18.5. 



Colombian specimens of Tangara cayana, including examples from both 

 sides of the Eastern Andes, are readily separable from a series from French 

 Guiana by their larger size and conspicuously paler general coloration, 

 this particularly evident in the males. They can not be referred to the form 

 cyanolaima of Bonaparte, said to be from eastern Peru (Rio Negro), since 

 this is described as being brighter throughout, with the blue of the throat 

 very conspicuous, which is certainly not the case with the Colombian 

 birds. I accordingly have no alternative but to give the latter a distinc- 

 tive name, since their characters are obvious and constant.

Thraupis palmarum atripennis, subsp. nov. 



Similar to Thraupis palmarum melanoptera (Sclater) of Guiana, Brazil, 

 Bolivia, etc., but somewhat smaller and generally darker, the wings blacker 

 and more uniform, and tail darker. Wing (type), 93; tail, 69; bill, 13.5; 

 tarsus, 20.5. 



Birds of this species from Costa Rica and Colombia (west of the Andes) 

 differ from a series from Guiana and the lower Amazon in their rather 

 smaller size and darker coloration throughout, the wing-coverts and bases 

 of the remiges being dull dark green (between vetiver green and grayish 

 olive), while the head is duller, darker green, and the gloss of the body- 

 plumage in adult males is more purely bluish, less purplish in tone. The 

 remiges have practically no lighter edgings, even in fresh plumage; the 

 tail is darker also. The Tanagra melanoptera of Sclater, based on the 

 bird of eastern Peru (which is undoubtedly the same as that of eastern 

 Colombia and of Bolivia), certainly does not apply to the present race, 

 although so given by all recent authors, and a new name is required, which 

 I here supply.

Piranga saira rosacea, subsp. nov. 



Similar to Piranga saira saira (Spix) of Brazil, but male much paler, 

 more pinkish throughout. The back is between Kaiser brown and ferru- 

 ginous, brightening into English red on the pileum; the ventral surface is 

 between flame scarlet and orange chrome in the brightest individual, and 

 Mikado orange in the palest. Females are indistinguishable in any way. 



The discovery of a distinct race of saira so close to the range of the typical 

 one (which we have from the Rio Quisera, in the Province of Velasco, north
