Obs. Species P. viridi quoad alarum tectricum colorem 

 castaneum affiuis, sed valde distincta. 



Unfortunately Mr. Whitely obtained only a single female 

 specimen of this obviously distinct species^ which seems to 

 be allied to the Brazilian P. viridis ; for, besides the upper 

 surface being olive, as in that bird, the wing-coverts are cin- 

 namon, as in the female of Bahia specimens of P. viridis. 

 P, griseignlaris, however, may at once be distinguished by its 

 grey throat and breast, the latter in P. viridis being yellow, 

 and by the absence of the grey collar which separates the 

 olive head from the back in the Brazilian bird. Judging 

 from analogy, the male will prove to have the top of the head 

 black and the wing-coverts olive, like the back.

The bird here described differs from every species with 

 which we are acquainted in having a grey head and grey 

 breast and throat, rendering it more distinct at first sight 

 than many acknowledged species.
