DRYOSCOPUS MALZACII 347 
Heuglin’s Puff-back Shrike is found throughout north- 
east and most of central Africa, from Eritrea and the 
White Nile to the Shari region east of Lake Chad, and south 
to Ruwenzori and Kavirondo in British East Africa. In the 
case of the females only it is possible to distinguish two sub- 
species :— 
D. malzactii from the Nile Valley and Abyssinia, with 
paler under parts and white throats and under tail-coverts. 
D. m. nyanse from Uganda and the Shari River region, 
with the under parts and edges of the wing tawny and more 
richly coloured. 
This Shrike was first met with by Salt in Abyssinia, and 
was mentioned by him in his travels, but neither he nor 
Riippell nor Blanford recognized its distinctions from the 
South or West African species of the same genus. 
Heuglin’s description was founded on a female from the 
country of the “Bohr” or “Schir” negroes- of the Upper 
White Nile (z.e., between the Sudd country and Gondokoro) ; 
subsequently Hartlaub described what appears to be the 
same bird from an example obtained by Emin at Lado, not 
far off. Neumann, in his revision of the Bush Shrikes, recog- 
nized three subspecies of D. malzacii: the typical subspecies 
from the Nile Valley, to which he assigned Hartlaub’s 
D. cinerascens with pale yellow under parts; D. m. nyanse 
with the darker and more richly coloured under parts; and 
D. m. erythree with hardly any yellowish on the under parts, 
which are described as dirty white. 
An examination of the large series in the British Museum 
shows that there is a good deal of variation among the 
Abyssinian birds, and that some of them are almost as richly 
coloured as those from Uganda, and it seems best to make 
only two races. 
In southern Abyssinia and Gallaland this species was met
