as the belly strongly washed with olive- or rnfescent brown. Sometimes a few 

 narrow, blackish cross-bands are to be seen hero and there on the mantle. The 

 young male (No. 320) is even more decidedly rnfescent both above and below, with 

 the forehead and crest nniform dnll chestnut. 



Young females differ from adult ones by liaving the npper wing-coverts 

 distinctly rnsty brown with the black subapical bands ranch narrower, and the 

 apical margins less defined as well as of a deeper, more cinnamomeous tinge. 



A. koffmannm is as yet only known from the right bank of the Rio Madeira. 

 It is strictly congeneric with A. (/i/miwps (Ridgw.j,* A. cristata (Pelz.),t and 

 A. berlepschi Snethl., J all of which agree perfectly in structural details, but I do 

 not see how this group can be separated generically from Anoplops.

Left bank of the Rio Madeira : Hnmaytha. Also obtained at Cachoeira, Rio 

 Funis, on the Rio Jurua, and near Sarayafu, Eastern Ecuador (type). When 

 Connt Berlepsch, some years ago, sent me one of the Purus specimens for com- 

 parison with the type in the British Museum, I at once suggested the probability 

 of their being male and female of tlie same species. This view has been fully 

 confirmed by the sexed specimens which Mr. Hoffmanns, shortly afterwards, 

 forwarded to the Triug Museum. G. purusianus is, therefore, a synonym of 

 A. melanosticta, the supposed specific characters being those of tlie adnlt male. 



An immature male from the Rio Jurn^ (in the Museu Paulista), which I have 

 lately had an opportunity of inspecting, has the belly very nearly as dark sepia- 

 brown as the type from Sarayacu.]
