In the males the upper tail-coverts are slate-grey with a black snbterminal 

 band and a white apical spot ; only in one from Hnmaytha (No. 1143) black tipped 

 with white as in II. p. poecilinota and H. p. lepidonota. The cinereous wash on 

 the base of the central tail-feathers, however, is not a constant character, for it 

 is not present in quite a number of specimens. The colour of the under parts 

 is also rather variable, some examples being quite as dark as //. p. lepidonota, 

 while others agree with 11. p. poecilinota. 



The two females from Hnmaytha are rather darker cinereous below than those 

 from Borba. In No. 1 182 (Hnmaytha) the throat is cinereous like the rest of the 

 under parts; in the others much paler greyish white, or even white {e.g. in No. 1433). 

 The forehead and sides of the head are clear ferruginous, and there is always a 

 large concealed white interscapular patch.

The males have the belly of the same clear slate-grey as specimens from 

 British Guiana, Cayenne, Itaituba, and Telle, hence much lighter than in 

 //. I. leucophrys, of the Andes. The white frontal band is fully as broad as in 

 Guiana skins. 



In the female of this species the lower mandible is always dnsky or brownish 

 black, the upper wing-coverts show small but well-defined buff apical spots, and 

 there is a very distinct, clear ferruginous superciliary stripe above the eye and along 

 the upper margin of the deep black eaF-coverts.
