358 DRYOSCOPUS BOCAGEIL 
varies somewhat in intensity, but is cinnamon rather than ochraceous. Iris 
dark-brown, bill black, feet slate-blue. Length 6:5 inches, wing 3:1, tail 2°85, 
culmen 0:50, tarsus 0:90. N’Dalla Tando, type, 3, 5. 8. 08 (Ansorge). 
Bocage’s Puff-back Shrike is confined to Camaroon and 
Spanish Guinea, and is replaced by the two closely allied 
subspecies, Jackson’s in Uganda, and Ansorge’s in North 
Angola. 
The type of Bocage’s Puff-back was collected by Zenker 
at Jaunde in German Camaroon, and it has since been 
obtained by Bates on the River Ja in the southern part of 
the same colony. This observer states that it is known 
as the ‘“Asanze,” and makes the following remarks: “All 
were in the small trees bordering cultivated ground. One of 
them was heard making a call much like that of D. senegalensis. 
The female was shot just after leaving the nest, in a little tree 
on the border of a patch of maize. The nest was shallow, 
cup-shaped, and composed entirely of the dry tendrils of a 
vine woven together.” 
Reichenow has recently recorded this species from Bebai 
on the Rio Benito in Spanish Guinea. 
The type of D. jacksoni is stated in the original description 
to have been obtained at Mount Elgon, but the type is labelled 
Nandi, which is some distance further south. In the Jackson 
collection there are additional examples from Kazi and the 
Mabira Forest, both in the Uganda Protectorate, and it was 
also obtained, according to Reichenow, by Grauer at Entebbe. 
The third form of this species, D. b. ansorgez, is only known 
from N’Dalla Tando in north Angola, where Dr. Ansorge 
collected, in addition to the type, a series of five males and 
five females between the dates August 2 and December 23, 
1908.
