The fact that ihese birds ail bave the characleristics of /-'. /. togoen- 

 sis rather than those of F . l. leucolaima is verv reniarkable. It is 

 vet another case ot a specialised race having its contiiuious range 

 broken (split in two), by a différent fomi. 



The last review of the P. leucolaima group appeared in the /oiir- 

 tial fi'ir Ornithologie, 1907, pp. 346-348 froni the pen of Professer 

 Neumann. NiXMANN rccognises three races and I agrée with his 

 revision as tar as it goes : three races are found in West Africa if 

 \ve accept the Fernando Po bird as a valid race. 



1. — PoGONiri.US LEUCOLAIMA LEUCOLAIMA. 



Barbatula leucolaima Verr., Rev. Mag. Zool., 185 1, p. 263. — 

 Tvpe localitv : Gaboon. 



Range. — Cameroon (including Canieroon Mountain;, Gaboon, 

 Northern Angola, Western Belgian Congo (Ubanghi river). 



Distinguishing characters. — Upper-parts dark glossv blue ; 

 upper breast, throat and crop grev ; rest of underparts greenish 

 yellow ; rump pale sulphiir-yellow. 



2. POGONIUI.US LEUCOLAIMA TOGOENSIS. 



Cf. supra. 



Synonyin. — Barbatula sharpei O. Grant (Gold Coast) is an 

 aberrant form of the above. 



Range. — Ganibia, Sierra Leone, Portuguese Guinea, Gold 

 Coast, Southern Nigeria, N. W. Belgian Congo. The bird inhabit- 

 ing the Uelle river district of the North Belgian Congo as far as 

 the Kibali river, is indistinguishable from the above. We should 

 hâve expected it to belong to the saine race as that which inhabits 

 Canieroon, but it undoubtedlv bas the bright vellow bellv ot the 

 Upper Guinea bird.
