320 Mr. W. E. de Winton on 



A. harharus, var. massaicus ; it has nothing to do with 

 A. barbarus, but is very closely related to A. pulchdlus. 



12. ArvicantJiis abyssinicus^ Riipp. 



Six specimens of various ages. 



13. Leggada minutoides, Sm. 



One. This name is used for the smaller chestnut-brown 

 form. 



14. Leggada muscuhides, Teram. 



One. This name is used for the larger grey-brown form. 



The two forms seem to be found side by side in various 

 parts of Africa ; but we must wait for more evidence before 

 positively stating their relationship or otherwise. 



XXXV. — On a Collection of Rodents from Angola. 

 By W. E. DE VYiNTON. 



Through the kindness of Prof. Barboza du Bocage, of the 

 Lisbon Museum, I have been entrusted with the working out 

 of a number of rodents from Angola to be ultimately presented 

 to the British Museum. My primary object was to endeavour 

 to explain the various forms of Geary chus found in this 

 region, our Museum being very well supplied with forms 

 from other parts of Africa. The results of my work are 

 given below, and it will be seen that the Georychi were not 

 the only animals of interest in the collection, a dormouse and 

 a mouse being described as new. 



Grapkiurus angolensis^ sp. n. 



General colour drab-brown mixed with whitish, most of 

 the underfur appearing to be tipped with the latter colour. 

 All the underparts creamy white. Bases of all the body-fur 

 above and below slate-black. Upper lips, cheeks, throat, 

 hands, and feet entirely cream-white. Ears sparingly clothed 

 with short brown hairs. Tail drab-brown, flecked with 

 white, most of the hairs being tipped with white; these pale 

 tips increase in length towards the distal portion, till at the 

 extreme end the hairs may be entirely of the pale colour, 

 forming a cream-white tag. The tail is bushy and flattened 

 beneatli ; the hairs increase in length, graduating from the 

 body to the tip. 



Mammae 2 — 2 = 8, 1 axillary, 1 behind the elbow, 1 on the 

 extreme front of groin, 1 on groin.
