1 6 WROUGHT ON, Collection of M animals from Rhodesia. 



then with a yellowish white ring not quite so broad, the 

 terminal third being black interrupted by a narrow 

 (2 — 3 mm.) white ring, the general effect being a pale 

 grizzled grey. The cheeks, which in typical annulatus 

 are pale buff, are here white, and the streaks above and 

 below the eye are in these specimens a bright silvery 

 white and most conspicuous. The feet also differ from 

 those of annulatus in wanting the yellow (or buff) tinge. 



The skull is rather larger in all dimensions than that 

 of annulatus, the bullae especially are markedly larger ; 

 but the length of the upper molar series is the same in 

 both forms. 



Properly measured specimens of annulatus of the 

 same age as this adult specimen are not available, but one 

 somewhat younger from Gambia is described by the 

 Collector as head and body 190, tail 210, hind feet 48, 

 ear 16.
