The type came from Tanganyika and was distinctly 

 smaller, in all dimensions, than these specimens, but there 

 is a specimen from the Nyika Plateau, British Central 

 Africa, which is almost as large. 



" I had heard of the existence of this species long 

 before I succeeded in obtaining specimens. It prefers, 

 somewhat open sandy country, living in burrows. It is 

 exceedingly active. The Asenga call it 'Mtoroka' and 

 state that adult males are much larger than either of the 

 above specimens."

These specimens are quite the same in all essential 

 characters as a series from Nyasa in the British Museum 

 Collection. No species have been described from this 

 part of Africa and the material available for examination 

 is rather meagre. It seems to me best to refer these 

 specimens, at any rate for the present, to one of the two 

 South African species. Skulls which have been identified 

 as mesomelas Brants are consistently distinguishable by 

 the shape of the frontals from the present specimens 

 which I therefore call provisionally pumilio. 



"This small species is said to be especially common 

 in Banana plantations. ' Msuntwa ' of the Lake tribes as. 

 well as of the Asenga."
