The larger race will have to stand as E.f.franqueti, the 

 smaller race may be known as 



Epomops franqueti strepitans, subsp. n. 



Type, <$ ad., skin and skull, Asab:i, S. Nigeria; presented 

 by Dr. W. H. Crosse; B.M. 95. 5. 3. 7. 



XIII. — New African Mammals of the Genera Cricetomys and 

 Procavia. By R. C. WROUGHTON. 



A CAREFUL comparison of the skins and skulls of specimens 

 of the genus Cricetomys shows that at least two new forms 

 require names. Until more complete material is available 

 for study it seems most convenient to rank them as geogra- 

 phical races of C. gambianus. 



Cricetomys gambianus emini, subsp. n. 



A Cricetomys closely resembling C. gambianus (s. s.) in size 

 and colour; with stouter teeth, larger palatal foramina and 

 bullee. 



Fur rather harsh, 15 mm. long on back ; individual hairs 

 greyish white, with apical third brown. General colour 

 above Mars-brown, paling to near " vinaceous cinnamon " on 

 flanks ; belly pure white. Arms and legs like back above, 

 ringers and toes pure white. Slightly less than basal half of 

 tail like back, remainder white. 



Skull as in typical gambianus, but teeth larger, palatal 

 foramina longer, bullse somewhat smaller. 



Dimensions of the type (measured on the skin) : — 



Head and body (c.) 400 mm. ; tail (c.) 370; hind foot 72. 



Skull: greatest length 75; basilar length 65; zygomatic 

 breadth 36; nasals, length 32; palatal foramina 9; dia- 

 stema 25 ; greatest breadth of m 1 3'5 ; upper molar series 11*5. 



Hab. Gadda, Mombattu. 



Type. Adult male. B.M. no. 87. 12. 1. 55. Collected 

 February 1884, and presented to the Natural History Mu- 

 seum by Em in Pasha. 



The stout teeth and large palatal foramina distinguish 

 emini from typical gambianus, and its bright colouring 

 prevents any confusion with the next form.
