Distribuiio/i of the Crested Cuckoos. 



403 



races are to be met with. The first of these, C. caroli, is a 

 long-tailed form of C.jacobinus, with distinct blackish streaks 

 on the throaty showing an approach to C. cafer. In the 

 extreme range of the species in South-eastern Africa, the 

 specimens of Pied Cuckoo are remarkable for a greyish 

 shade on the throat and breast, which seems to be a constant 

 character in all specimens from British Caffraria and the 

 adjacent parts. This race has been called by Cabanis and 

 Heine C. hyjjopinarius -, but it seems to me that a perfect 

 gradation takes place between this race and the true C. jaco- 

 binus, which also occurs in Natal and the Transvaal, the 

 majority of the specimens being absolutely indistinguishable 

 from Indian examples. The geographical distribution o£ 

 these two sub-species is given below. 



The following is a summary of the measurements of the 

 wings of the skins in the British Museum. African birds 

 appear to vary considerably in their dimensions, as will be 

 seen from the followinsr : —
