brown towards the tip of the outer and the base of the inner 

 web. The white outer tail-feathers are apparently charac- 

 teristic of immaturity ; the adult birds having the outer 

 feathers white, tipped and more or less margined with 

 brown. 



Dr. Reichenow [Vog. Air. ii. p. 114(1902)] has united 

 with this species P.peasei Grant, which has the outer feathers 

 dark brown, with oidy an indication of a narrow white stripe 

 next to the shaft on the basal half of the inner web. This 

 is evidently a mistake, as is also his synonym P. za/nbesice 

 Shelley, which belongs to the olive-backed section ! 



Dendropicus ZANZIBAR! Malh. 



Three specimens collected at Mulema and one at Burumba 

 are undoubtedly typical examples of this barred-backed 

 species. They agree exactly with specimens from Zanzibar 

 procured by Fischer and named D. hartlaubi. Whether 

 they are really identical with typical D. hartlaubi Malh., 

 from Natal, is another question. 



Dendropicus lafresnayi Malh. 



An adult female of this species was procured at Burumba. 

 It may be at once distinguished from the female of D. zanzi- 

 bari by the uniform colour of the back. 



Mesopicus pyocephalus (Swains.). 



Mesopicus pyocephalus Grant, Ibis, 1902, p. 425; Sharpe, 

 Ibis, 1902, p. 641. 



An immature male and an adult female from Mulema 

 belong to this form, which ranges northward through the 

 Niam-niam and Siik countries to the White Nile. It has 

 been described as M. goertie centralis Reichenow. 



Cerchneis ardesiaca (Vieill.). 



Cerchneis ardosiacea Reichenow, Vog. Afr. i. p. 636 (1901) . 



A fine male of this rare species was procured at Msozi, on 

 the western shore of Victoria Nyanza, in February. The 

 wings are in moult, and all the primary quill-feathers have 

 been renewed except the two outer pairs.
