Species of the Genus Pipra. 27 



middle of the abdomen being dull greyish. Wing 65-08 ; 

 tail 32-34 mm. 



Typical Bogota skins are, as a rule, duller and deeper black 

 without the metallic gloss so conspicuous in Peruvian 

 specimens ; but one is quite indistinguishable from the latter. 

 Specimens from North Peru (Chirimoto and Guayabamba) 

 and East Ecuador are practically identical ; two males from 

 Huanuco belong likewise to P. I. coracina, and are very 

 different from the subspecies found in the Chanchamayo 

 region. P. I. coracina seems to be an inhabitant of high 

 elevations, where it apparently replaces the typical form. 

 It is interesting to note that a female from Chyavetas is 

 referable to P. I. coracina, while the specimens from Xeberos 

 and Chamicuros belong to typical P. leucocilla.

$ ad. — Easily distinguished from P. I. coracina by its 

 louger tail and by the feathers of the occiput being so 

 much elongated as to form a conspicuous full crest. These 

 lengthened feathers are, moreover, pure white, and entirely 

 lack the blackish bases to be seen in typical P. leucocilla and 

 P. 1. coracina. Wing 69-70 ; tail 36 ; bill 10 mm. 



? ad. — Similar to that of P. I. coracina, but with the tail
