182 On two new Birds from Northern Peru. 



wing, whereas in B. gustavi tlie slioulders, or the anterior least 

 upper wing-coverts, the anterior margin of the wing, the first 

 of the coverts of the primaries, and the anterior under wing- 

 coverts, are of a fine golden yellow. It appears also that in 

 the new species the chin is of a paler orange-rufous. The 

 front is not suffused with yellowish, as in B. jugidaris, and 

 the back appears to he of a darker green ; the wings, too, 

 are a little shorter. 



As well in coloration as geographically, B. gustavi seems 

 to be intermediate between B. jugularis and B. chrysosema, 

 the latter species showing also some yellow in the wing, 

 but being further distinguished by possessing an orange border 

 to the front. 



The three specimens collected by Mr. Garlepp do not show 

 any differences in their coloration.

This is evidently a new species of Phaiithornis, nearly allied 

 to, but easily distinguishable from, P. striigularis by its larger 

 size, blacker throat, deeper fulvous abdomen, pure white, not 

 fulvous, under tail-coverts, and narrow white borders instead 

 of broad fulvous tips to the outer tail-feathers. The feathers 

 in the middle of the breast are broad and greenish black ; 

 they form a tuft somewhat as in the male of P. jjygniaus 

 and its allies, while such a tuft is altogether wautiug in 

 P. striigularis.
