middle of the abdomen are white, sometimes tinged with buffy, but 

 always in strong contrast with the flanks, lower abdomen, and under 

 tail-coverts, which are bright buffy clay-color. In the new form the 

 latter color spreads over the entire under parts as far as the throat, 

 the middle of the abdomen being merely a little paler. The size is 

 greater also, the bill especially, while the crown, which is dark plum- 

 beous, concolorous with the back in the Orinoco form, is margined later- 

 ally with a black stripe, meeting its fellow on the forehead. For com- 

 parison there have been available six adult specimens of true oreno- 

 censis from San Felix, Orinoco River, collected by Mr. Carriker in 

 February, 1910, and therefore fully comparable as to season. These 

 agree perfectly with Berlepsch and Hartert's figure of this form 

 (Novitates Zoologies, IX, 1902, pi. 12, fig. 3). 



Tangara guttata eusticta subsp. nov. 



Type, No. 28,895, Collection Carnegie Museum, adult male; 

 Boruca, Costa Rica, August 9, 1907; M. A. Carriker, Jr. 



Subspecific characters. — Similar to Tangara guttata guttata (Cabanis) 

 of British Guiana and northern Venezuela, but under parts much 

 more heavily spotted, especially the throat, the feather-edgings on 

 the throat and breast being pale glaucous green; green color of flanks 

 brighter and more extended; edgings of remiges and their coverts 

 inclining to beryl-green; and average size somewhat lesv. 



Measurements of type. — Wing, 67 mm.; tail, 49; exposed culmen, 11 ; 

 tarsus, 19. 



Remarks. — When Mr. Ridgway wrote the second volume of his 

 Birds of North and Middle America he had only one very unsatis- 

 factory specimen of this species from Costa Rica before him, which he 

 doubtfully referred to "chrysophrys" of Sclater. There are twenty- 

 two examples from this country in the Carnegie Museum, and the 

 acquisition of a series of specimens from other parts of its range has 

 shown that Mr. Ridgway erred in considering the Central American 

 bird to be identical with that from Venezuela, from which it differs 

 conspicuously in generally brighter coloration and much heavier 

 spotting below, besides being slightly smaller. These remarks are 

 based on five adult specimens from La Cumbre de Valencia, Lagunita 

 de Aroa, and Anzoategui — localities in northern Venezuela which 

 unquestionably pertain to typical "chrysophrys." A specimen from 

 Mount Roraima, British Guiana (No. 54,058, Collection Academy of
