 This species is in colour like T. immaculatus, of a uniform black , 

 but, whilst that has only a very insignificant white patch oa the 

 bond of the wing, the T. cethiops has the under wing-coverts as well 

 as the upper coverts close to the bend varied with white. Besides, 

 the bill is much shorter and stouter, and the whole bird is smaller 

 in its dimensions. Of T. immaculatus I make the corresponding 

 measurements: — Long, tota 7'<>, ahe 3'3, caudse 3*0, rostri a rictn 

 1-0, tarsi 13.

This Thamnophilus belongs to the typical division of the group 

 which contains T. nanus and its allies. It i> easily distinguishable 

 by its uniform cinereous plumage and black head, with the absence 

 of all markings ou the wings and tail. M. Verreaux'e collection 



contains a male not quite ailnlt and t\so females ofthis Bpecies.

Apparently a female of some species of this genua. A large I j

 inordinately thickened.
