river coUected by Dr Baikik, from Lokoja by W. A. Forbes; and 

 from Ibi (June 1904); near Pettu (August 1904); and near Katab 

 (August 1904), ail collected by Boyd Alexander. 



The typical species is represented in the British Muséum from 

 Gambia, Portuguese Guinea, Sierra Leone, Libéria, Gold Coast, 

 Northern and Southern Nigeria. 



The races of D. gmiihensis hâve been recently reviewed by 

 MessrsScLATER andPRAED(Ibis, 1918, pp.635-636)where the range 

 and distinguishing characters of the females are given. The only 

 other West African représentative besides the typical form is : 



Dryoscopus gambensis congicus ('). 



Dryoscopus congicus Sharpe, Ibis, iqoi, p. 39 : Condé, Gaboon. 



Range. — Portuguese Congo, Gaboon. 



Distinguishing characters. — Maies indistinguishable from 

 typical species ; females head darker grey than in D. g. gambensis ; 

 underparts brighter rufous-tawny, especially on the chest.

Nicator chloris chloris. 



Lanius chloris Valenc, Dict. Se. Nat., XL, 1826, p. 226. — 

 Type locality : Galam, Sénégal. 



Mr LowE shot four spécimens of the White-throated Nicator in 

 December, January and February 1920, while Mr Kemp had already 

 procnred the bird at Burutu, S. Nigeria in April, 1905. 



Oddly enough we hâve no spécimens from Northern Nigeria. 



There is a very large séries in the British Muséum from West 

 and Central Africa and I cannot distinguish any races throughout 



(') Herr H. Grote has, since this paper lias appeared in print, described another race 

 from West Africa : D. g. sextus. [Anz. Orn. Ges. Bay. 5 Dez. 1921, n' 5, p. 40 : Bobuni.
