DRYOSCOPUS SENEGALENSIS 341 
of white on the shoulder. On the other hand, a male from 
Bellina in the Mombattu country, collected by Emin, is quite 
indistinguishable from the series from Camaroon. 
Sjéstedt met with this bird at Bonga, a village on the 
Meme River in Camaroon, during the dry season, when he 
found it fairly common; he states that it keeps chiefly among 
the tops of the higher isolated trees, whence its ringing note 
can often be heard. As in other Bush Shrikes, the male’s 
clear flute-like note of two tones is instantly answered by a 
short, harsh, growling reply from the female. 
Mr. Bates, whose collections were made in the more 
southern portion of the same colony, states that it is called 
there “‘Seso,” and makes the following remarks: “ The vary- 
ing shades of black, grey and white on the backs of the 
females of this species has caused much perplexity. Sharpe 
recognized (doubtfully) two species among my birds, and 
Neumann thought there were two species found in Camaroon 
in which the males were alike, only the females differing. My 
large series of specimens, including those listed above, together 
with those in the British Museum from former collections, 
contains many adult males, but all with glossy black backs 
and wings, and pure white rumps, while the females differ in 
all degrees, from those with grey backs and wings and light 
grey rumps, to one almost like the male on the back and 
rump. It is not unreasonable to suppose the last was an old 
female, and that as females advance in age they become more 
like the males in plumage.” 
In the British Museum this species is represented as 
follows :— 
Camaroon—Etulen, River Ja, Bitye (Bates); Gaboon— 
(Verreaux, Ansell, and Bouvier); Belgian Congo—Yambuya 
(Jameson), Ponthierville (Carruthers), Mawambi in the 
EH. Congo Forest (Woosnam), and Bellina in the Mombattu 
country (Emin).
