new African Mammals. 193 



Skull : greatest length 18 ; front of canine to back of m 3 

 6-6. 



Hob. Upper Sheikh, Somaliland. Alt. 4500'. 



Type. Adult female. B.M. no. 9. 12. 17. 4. Original 

 number 237. Collected 13th November, 1909, and presented 

 by Dr. R. E. Drake-Brockman. Two specimens. 



The most striking character of this bat is its peculiar 

 whitish colour, other members of the group being generally 

 some shade of grey. Unfortunately the colour of the original 

 specimens of its nearest ally R. dobsoni, from Kordofan, can- 

 not be determined, but the difference in the skulls and teeth 

 is quite sufficient to separate the two. 



A number of B. acroiis, Heugl., were obtained at the same 

 time and place. 



Erinaceus hitidei, sp. n. 



Colour and other external characters as in E. albiventris. 



Skull markedly broader and heavier than in albiventris, 

 that of a female fully the length of an adult male albi- 

 ventris and much broader. Zygomata very much more 

 widely expanded, the zygomatic breadth 30 mm. as compared 

 with 27 in the broadest of six examples of albiventris. Nasals 

 narrow as in albiventris, not so broad as in sclateri. Prse- 

 maxillse more slanted backwards, touching the tips of the 

 frontal processes and shutting off the maxilla? from the nasals ; 

 in albiventris there is a naso-maxillary suture about 3*5 mm. 

 in length. Teeth larger and heavier throughout, and the 

 palate broader. Mesopterygoid fossa also decidedly broader. 



Dimensions of the type : — 



Hind foot 26 mm. 



Skull : greatest length 44; zygomatic breadth 30; nasals 

 11*5x2 2; intertemporal constriction 11*6; palatal length 

 25 ; breadth across palate, including m 1 , 18'2; breadth of 

 mesopterygoid fossa 3*5 ; length of upper tooth-row 21*5. 



Hab. Kitui, British East Africa. Alt. 3500'. A second 

 specimen from Machakos. 



Type. Adult female. B.M. no. 1. 5. 6. 6. Original num- 

 ber 67. Collected 24th January, 1901, and presented by 

 Di. S. L. Hinde. 



This hedgehog is no doubt closely allied to E. albiventris, 

 with which it shows all the important structural characters, 

 but may be distinguished by the differences in the skull above 

 described. When males are available for comparison the 

 discrepancy in size will no doubt prove to be greater than 

 now appears.
