386 Genera of Humming Birds. 



in their middle portion, not blackish as in P. longuemarei 

 and presenting a paler bronze tint to their bases. The next 

 following pair of rectrices possess a great amount of rufous 

 on the outer webs, and a slight suffusion on the inner web, 

 before the white tips. In P. longuemarei \\-\ç.xç. is none or but 

 little rufous tint on the submedian tail feathers. 



The outer tail feathers in P. nattereri, possess very long 

 rufous tips ; in P. longuemarei, there is a narrow white or 

 rufous border to the tip. The middle portion of these 

 rectrices in P. nattereri, is only slightly tinged with viol- 

 aceous on the inner web, while they are altogether blacker for 

 a long distance on both webs in P. lo?iguemarei. Besides, 

 the underparts of the body ane of a paler fulvous, the jugulum 

 only being slightly sufïused with rufous. The throat does not 

 show the large black spots so conspicuous in P. longuemarei. 

 In P. nattereri, they are either completely wanting or 

 invisible except at the extreme bases when the feathers are 

 raised. The top of the head is a paler sandy rufous-brown 

 The uppertail-coverts are nearly uniform dark rufous with no 

 trace of the green spots to be seen there in the other species. 

 The black tip of the mandible is reduced to a minimum, being 

 much shorter than in P. longuemarei. P. apheles Heine 

 comes very close, this species differing only by the pure black 

 and broad sub-apical band to the outer tail feathers and in its 

 shorter wings.

Habitat. — Brasilia ?

 only by the pure black and broad sub-apical band to the outer 

 tail feathers, and its shorter wings. 



Very doubtful species.
