as the belly strongly washed with olive- or rufescent brown. Sometimes a few 
narrow, blackish cross-bands are to be seen here and there on the mantle. The 
young male (No. 320) is even more decidedly rufescent both above and below, with 
the forehead and crest uniform dull chestnut. 
Young females differ from adult ones by having the upper wing-coverts 
distinctly rusty brown with the black subapical bands much narrower, and the 
apical margins less defined as well as of a deeper, more cinnamomeons tinge. 
A, hoffmannsi is as yet only known from the right bank of the Rio Madeira. 
It is strictly congeneric with A. gymnops (Ridgw.),* A. cristata (Pelz.),t and 
A. berlepschi Snethl.,t 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: Humaytha. Also obtained at Cachoeira, Rio 
Purts, on the Rio Jurnd, and near Sarayacu, Eastern Eenador (type). When 
Count Berlepsch, some years ago, sent me one of the Parts specimens for com- 
parison with the type in the British Museum, I at once suggested the probability 
of their being male and female of the same species. This view has been fully 
confirmed by the sexed specimens which Mr. Hoffmanns, shortly afterwards, 
forwarded to the Tring Museum. (G. purusianus is, therefore, a synonym of 
A, melanosticta, the supposed specific characters being those of the adult male. 
An immature male from the Rio Jurné (in the Musen Paulista), which I have 
lately had an opportunity of inspecting, has the belly very nearly as dark sepia- 
brown as the type from Sarayacu.]
