Nigerian hedgehog, and these are all very uniform with the 

 original series from near Lake Chad, having a skull-length 

 of about 43 mm., comparatively broad muzzles and evenly 

 expanded zygomata. The little specimen from north of 

 Sokoto, a fully adult male, appears therefore to be worthy 

 of specific separation. So far as I am aware, it is the 

 smallest hedgehog in the world. 



Atelerix kilimanns, sp. n. 



Allied to A. hindei, but smaller. 



Colour essentially as in hindei, with a number of the dorsal 

 spines white-ended, while the majority have drabby ends 

 with the extreme tip dark. Hairy parts of body white, the 

 muzzle and feet dark brown. Spines of back about 19 mm. 

 in length, dark at their absolute base, then with a 5-nim. 

 white band, a rather longer blackish one, a 3-mm. sub- 

 terminal one, and a dark extreme point. 



Skull of quite the same general shape as that of A. hindei, 

 broad, with comparatively short muzzle and evenly widely 

 expanded zygomata ; in albiventris the skull is narrower, 

 the muzzle longer and more slender, and the zygomata less 

 expanded. In sotikcs the nasals are of unusual length, and 

 the species is perhaps more nearly allied to albiventris. 



Dimensions of the type (measured in the flesh) : — 



Head and body 174 mm.; tail 15; hind foot 25*5; 

 ear 25. 



Skull: condylo-basal length 42 ; zygomatic breadth 28*3; 

 nasals 12*7 X 26 ; interorbital breadth 13'5 ; intertemporal 

 breadth 108; postglenoid breadth 22 - 2 ; palatal length 

 24*7 ; upper tooth-row 202 ; combined length of j*/ 4 , m\ and 

 m 2 96. 



Hah. Kilima-njaro. Type-series from Rombo, alt. 5300'. 



Type. Adult female. * JB.M. no. 10. 7. 2. 38. Original 

 number 1138. Collected 9th June, 1910, by Robin Kemp ; 

 presented by C. D. lludd, Esq. Fourteen specimens, 



The Kilima-njaro hedgehog is distinctly smaller than that 

 of Kitui, and may be distinguished even by the size of the 

 molars, the breadth of m 1 (anteriorly) being in hindei about 

 4*4 mm., while in hilimanus it is about a millimetre less. 

 Both are readily distinguishable from albiventris by their 

 broader and more rounded skulls. 



Paraechinus amir, sp. n. 



Size about as in P. macr acanthus. Colour and other 

 external characters very much as in that species, the head
