the whole extent of the rane;e given below. I agrée with Sci.ater 

 that Reichenow's A^. c. laemocyliis (J. f. O., 1909, p. 108, Béni 

 forest) cannot be recognised, as the character of the yellow spot 

 on each side of the throat extending right across the throat in a 

 continuons band is anything but constant. It is perhaps more 

 marked in birds from the Semliki valley district, but even in 

 typical birds from Fort Béni the spots do not entirely meet and 

 this supposed character is présent in certain spécimens from other 

 widely separated districts in Africa. 



Range. — In the British Muséum we hâve examples of iV. c. chiot is 

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

 Southern Nigeria, Cameroon, Gaboon, North and South Belgian 

 Congo, the Semliki valley and Uganda. 



(A handsome but rather shy shrike whose note « Tuck-Tuck » is 

 so frequently heard in dense foliage. — W. P. L.) 



I consider the East African représentative race known as the 

 Zambesi Nicator to be a subspecies : 



NiCATOR CHLORIS GULARIS. 



Nicator gidaris Finsch and Hartl., Vôg. Ost. Afr., 1870, p. 360 : 

 Tête. 



Range. — Kenya Colony, Tanganyika Territory, Nyasaland, 

 Rhodesia, Port E. Africa, Zambesi River, Zululand. 



The only other member of this genus is a small species confined 

 to a small part of West Africa. It is : 



Nicator vireo. 



Nicator vireo Cab., J. f. O., 1876, p. 333 : Chinchonxo. 



Range. — Cameroon, Belgian Congo (Congo River and Aru- 

 whimi River), Northern Angola. 



Distinguishing characters. — May be knovv at once by its small 

 size, wing 70-82 mm. The colouring of the head and throat is 

 also différent from N. chloris.
