Type. In the British Museum. (? ad, Beoumi, Ivory 

 Coast (650 £t.), 21st November, 1922. W. P. Lowe and 

 H. R. Hardy colls. (No. 34). 



Obs. This is the first time the species has been obtained in 

 Upper Guinea. 



Phyllastrephns eburneus, sp. nov. 



This new Bulbul seems to be most nearly allied to 

 P.poensis. It closely resembles that species in the colouring 

 of the upper parts, which are olive-brown rather than 

 olive, washed with rufous, and becoming quite rust-coloured 

 on the rump ; upper tail-coverts and tail exactly the same as 

 in P.poensis. The head is darker than the back, but is not so 

 dark as in P. poensis. On the under surface the new species 

 cannot be compared with P. poensis. It lacks the dark 

 breast of that species, and is almost uniform greyish-olive, 

 not unlike Andropadus gracilirostris, but much greener. 

 The throat is very pale greenish-white, and the feathers of 

 the throat and breast have very distinct white shaft-streaks ; 

 the flanks are brownish-olive and the under tail-coverts pale 

 brown as in P. poensis, which species it also resembles in the 

 colour of the under wing-coverts and quill-lining. The bill 

 is rather heavier than P. poensis, less slender and broader at 

 the base. The sexes are alike. Upper mandible black, lower 

 bluish-white ; feet plumbeous ; iris hazel. 

 Bill 15, wings 75-83, tail 75, tarsus 21 mm. 

 Type. In the British Museum. Beoumi, Ivory Coast, 

 11th December, 1922. W. P. Lowe and H. R. Hardy 

 colls. (No. 231). 



Obs. I have recently worked through and separated into 

 races the entire group of African Bulbuls in the British 

 Museum, and cannot find anything resembling the bird here 

 described, nor can I identify my specimens with any pub- 

 lished description, though I fully realize the difficulty of 

 naming members of the gennsP/i i/llasti'ephus from literature. 

 The bird listed in my " Birds of Southern Nigeria " (Rev. 

 Zool. Afr. ix. p. 395) as Pkyllastrephus (species uncertain) 

 must be assigned to the species named above.
