“Tris brown or greyish brown, feet grey or plumbeous, bill black.” 
The adult ¢¢ differ from H. p. poecilinota, of which the Manich Museum 
possesses a very large series from Cayenne and the Caura Valley, by their con- 
siderably darker slate-grey under parts, and by having the white interscapular 
patch much more extended, ‘The colour of the upper tail-coverts, however, is 
variable and cannot be used as distinctive character. The females are typical (for 
description see Nov. Zool. xiii. p. 372) ; the colour of the throat varies from white to 
cinereous. : 
Hi. p. griseiventris is only known from Teffé, Rio Solimoéns, and the Rio 
Madeira where it inhabits both banks, but it has not yet been found farther to the 
east, e.g. on the Tapajéz.
