19. pionus. 329 



Young. Much greener than the adult on the head ; forehead 

 reddish ; the blue cross band on the lower throat less developed. 



Huh. South-eastern Brazil and Paraguay. 



The existence of this species in British Guiana appears to 

 me very doubtful, and most likely the birds attributed to it by 

 Schoniburgk were young, with reddish forehead, of P. menstruus. 

 The type of P. maximiliani with a reddish frontal band is no doubt 

 a young specimen of the bird called P. jlavirostris by Spix.

Very much like P. maximiliani, from which it differs, 1st, in 

 having the feathers of the pileum from the forehead green, with dark 

 edges, so that only the lores are black ; 2nd, the chin aud a band 

 across the throat of a red vinous colour, instead of blue ; 3rd, the 

 green colour of the upper and under parts more olive-brown. {Mus.

()/'.<. This species differs from P. jlavirostris (Spix) in the following particu- 

 lars :— 1. The leathers of the back and the wing-coverts are of a brighter green. 

 2. The feathers of the pileum are bright green, scarcely edged with blue. 3. The
