glossy dark green,

" Of P. cumanensis I have examined a splendid series of 

 about 20 specimens in the Tring Museum from British 

 Guiana, the Orinoco- Caura region, R. Napo, and N.E. Peru. 

 The sexes in this species are alike in colour, but the females 

 are very much smaller. 



" From P. jacutinga (Spix) the Trinidad form differs in 

 having the throat and fore-neck naked and in lacking the 

 white margins to the feathers of the lower parts. 



" Mr. Grant, when describing the Game-Birds for the 

 c Catalogue of Birds/ united P. nattereri, Rchb., from Matto- 

 grosso with P. cumanensis, owing to the fact that he had no 

 specimens of the former. I exhibit one specimen from 

 Paraguay which agrees very well with Reichenbach's de- 

 scription and is obviously distinct from P. cumanensis. It 

 differs from the latter in having the head and crest of a pure 

 white (instead of buff), with narrow brownish-black shaft- 

 lines, and in having two broad white stripes on the hind- 

 neck, extending to the nape and separated, whereas in 

 P. cumanensis the buff stripes are much shorter on the 

 occiput, and end in a line with the tips of the crest-feathers. 

 P. nattereri possesses on the fore-neck a free, narrow, pointed 

 wattle, about 20 mm. in length, while in P. cumanensis the 

 wattle is joined to the throat for the whole of its length 

 (about 6 mm.), and resembles a dewlap." 



[Mr. Ogilvie-Grant pointed out that a specimen in the 

 British Museum (Peru, Gould Collection) agreed perfectly 

 with the above description of P. nattereri^ but the series of
