240 FISCUS 
Adult female. Differs only in the flanks being washed with rufous. 
Wing 3:2. Nyika Highlands, ? 6.95 (A. Whyte). 
Sousa’s Shrike ranges from the Congo into Benguella and 
Nyasaland. 
The most northern known range for this species is 
Leopoldville on the Lower Congo, where it has been obtained 
by Bohndorff. In Angola both Mechow and Schiitt met with 
it at Malandji, and in Benguella the type was discovered at 
Caconda by Anchieta, according to whose notes it is known 
to the natives as the ‘“‘ Numbotue,” and at Quindumbo 
as the “ Undola’’; he also collected specimens at Galanga. 
It ranges eastward into Nyasaland, from whence there are 
specimens in the British Museum from the Nyika highlands 
(Whyte), Bulwa (A. Sharpe), and the Tanganyika Plateau 
(Manning), probably collected by the natives, which may 
account for our having no notes regarding the habits of this 
interesting species. 
Genus III, FISCUS. 
The members of this genus may be readily recognized as a rule by the 
black on the hinder half of the head extending down the whole length of 
the neck or back, while the sexes are distinguished by the females alone 
having some rufous on the flanks; one at least of these characters being 
always present. In other respects and in structural characters they 
resemble Lanius. ;

The genus has generally been included in Laniuws owing to the many 
characters common to both, but it appears to me deserving of recognition. 
It is essentially Ethiopian, one species only, F'. nubicus, ranging to the 
eastern shores of the Mediterranean and into southern Persia. This latter 
species, with J’. newtoni from St. Thomas Island, form a readily distinguish- 
able group, the rump and upper tail-coverts being of the same black shade 
as the upper back, hind neck and crown; they also differ from the other 
members of the genus in the females not having more rufous on the flanks 
than the males. The remaining members of the genus are divisible into
