Adult male. Very much like the male of P. passerina from Bahia 

 District, but smaller, darker and purer green : forehead and cheeks 

 brighter or emerald-green ; ultramarine-blue colour on the rump, 

 and wings a shade paler ; bill thicker and more robust : " irides 

 yellow " (Hauxwell) ; bill whitish ; feet dusky flesh- colour. Total 

 length about 5 inches, wing 3*1, tail 1*4, bill U - o, tarsus 0*41. 



Young (type of P. crassirostris). Differs from the adult in having 

 the rump green (a little brighter than the rest of the upper parts), 

 and the under wing-coverts also green ; a few blue feathers scat- 

 tered along the carpal edge, only one feather of the bastard-wing 

 blue, and the outermost greater wing-coverts green.

Through the kindness of Dr. Stolzraann, I have been able to 

 examine the type of P. crassirostris, and find that it has nothing 

 whatever to do with P. guianensis, with which it has been com- 

 pared by Taczanowski. It is an immature bird, as shown by a 

 few blue feathers along the carpal edge, scattered among the green 

 ones ; it has the primary-coverts, the inner primaries, and the 

 secondaries blue, exactly like P. passerina, the rump of a brighter 

 green than the rest of the upper parts, and the under wing-coverts 

 green. I feel pretty sure that its rump and under wing-coverts 

 would have become blue, as in the adult specimens from Nauta and 

 Samiria, mentioned below, if the bird had lived.
