"Iris brown or greyish brown, feet grey or plumbeous, bill black." 



The adult S S differ from //. p. poeciUmta, of which the Munich Museum 

 possesses a very large series from Cayenue and the Canra 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 tyj)ical (for 

 description see Xoc. Zool. xiii. p. 372) ; the colour of the throat varies from white to 

 cinereous. 



H. p. griseicentris is only known fmm Teffe, Rio Solimoens, and the Rio 

 Madeira where it inhabits both banks, l)iit it has not yet been found farther to the 

 east, e.g. on the Tapajux.
