Hab. New Granada. 



This species was first described by Gould as above cited ; 

 and a few years later Bourcier gave to it the name of aspasice, 

 evidently not being aware that Mr. Gould had already charac- 

 terized it. In 1860 Mr. Gould bestowed on it another name, 

 that of zonura. This, in our opinion, after the examination of 

 the type, kindly lent to us by Mr. Gould, is in no way dis- 

 tinguishable from P. griseigularis, of which we have a series 

 of specimens before us, and amongst them Bourcier' s type of 

 P. aspasice. 



Mr. Gould, in his remarks upon P. zonura, states that one 

 of its characters is the " deep black colouring of the tail-fea- 

 thers." We find in the specimens before us that this must 

 not be relied upon as indicating any specific distinctness, as, 

 although some have these feathers black like Mr. Gould's 

 type, others exhibit a greenish shade, but in every other par- 

 ticular are identical. 



We have examined the following specimens : — 



Two, New Granada (Bourcier), one of which is the type of
