Pastaza as T. oseryi, comparing it with P. anthophilus and 

 P. philippii. This species has generally been recognized as 

 distinct from Mr. Gould's P. hispidus ; but on comparing the 

 type of that species with several specimens from the Upper 

 Amazon, we do not find sufficient differences to separate them. 

 Mr. Gould's figures of both, in his monograph, show a distinct 

 arrangement of markings on the throat ; but we do not per- 

 ceive this to be the case, as all the specimens before us agree 

 in the coloration of this part, even Mr. Gould's type having 

 a white line down the centre of the throat, although the fea- 

 thers are so disarranged that at first sight it appears to want 

 this character. The only difference appreciable is that the 

 type of hispidus has a somewhat longer bill, and a very little 

 longer wing ; but as the length of bill in this species is well 

 understood to be of no specific value, we do not deem it in 

 this case worthy of consideration. The general coloration 

 of all the specimens is identically the same. Mr. Lawrence, 

 overlooking M. Bourcier's description of P. oseryi, and misled 

 by Mr. Gould's plate, redescribed this species as P. villosus. 

 We have examined the following examples : — 



Pebas, Peru: two (Hauxwell), Mus. S.&G.; one (Haux- 

 well), Mus. D. G. E. ; one (id.), Mus. P. L. S. 



Peru or Bolivia: one (Bridges), Mus. J. Gould (tvpe of 

 species) .

 p. 139; id. Mon. Troch. pi. 20. 



Hob. Environs of Quito (Jameson); Pallatanga (Fraser). 



This is a very distinct and well-marked species, and has its 

 nearest ally in P. pretrii. 



The following are our specimens : — 



Ecuador: one (ex Gould), one (Buckley), Mus. S. & G. ; 

 one (ex Gould), one (Buckley), Mus. D. G. E.» 



Pallatanga: one, (Fraser) Mus. P. L. S.
