I/oIk ailanji Plateau, S. Nyasa. Alt. 5500'. 



Ti/pe. Adult female. Original number 205. Collected 

 2nd\May, 1910, by Mr. S. A. Neave. Presented by the 

 Entomolo^^ical llesearcli Committee. 



Apait tVom the pecidiar character.s of it.s molar.s, this 

 mountain-mouse may be readily distinguished by its soft fur, 

 dark colour, grey and buffy belly, parti-coloured feet, and 

 nearly naked tail. It is, perhaps, most nearly related to 

 E. tullheryi of W. Africa and E. dennia' of lluwenzori ; but 

 in any case the relationship is very distant. 



With regard to the teeth, I find a similar duplication of 

 tlie outer cusp of the middle lamina of m^ in a. -single example 

 (B.M. no. 4. 7. 1. 109) of E. tullbergi, while other specimens 

 liave no trace of it. For this reason I reserve judgment as 

 to the value of the character until further specimens of 

 E. delectorum are obtained. 



Uranomys owenij sp. n. 



A small West-African representative of the recently dis- 

 covered U. ruddi of Mount Elgon. 



General appearance more that of an Acomj/s^ less that of 

 a Lojilitironiys, than is the case with U. ruddi, but this may 

 be paitly due to the make of the skins. Fur crisp, not so 

 stifl' as in ordinary Aconiys, more so than in U. ruddi; hairs 

 of back about 11-12 mm. in length, a few longer hairs 

 (13—14 mm.) intermixed with them. General colour very 

 like that of many species of Acomi/s, between dull tawnv and 

 clay -colour; paler and more buffy on the sides. LJnder 

 BUiface white, the hairs white to their bases; in U. ruddi 

 they are grey basal ly. Ears finely haired, brown. Hands 

 and feet white. Tail scaly, finely haired, very like that of 

 an Aconiys, brown above, whitish below. 



Skull, apart from its much smaller size, very like that of 

 U. ruddi. 



Dimensions of the type (measured in flesh) : — 



Head and body 91 mm. ; tail Otj ; hind toot 16"5 ; ear 14. 



tSkull : greatest length 2G*2 ; basilar length 22*2 ; greatest 

 breadth 13'G ; nasals 8 ; interorbital breadth 45 ; breadth of 

 brain-case 11; palatilar length 13*5; palatal foramina 7"3 ; 

 upper molar series 4*7.
