XL1V. Descriptions of Two new Muridae prom. Central 

 and West Africa. By W. E. DE WlNTOX. 



THE examination of some specimens of West-African Muridas 

 lately acquired by the British Museum and kindly entrusted 

 to me for determination by Mr. Oldfield Thomas shows the 

 necessity for descriptions being drawn out and names given 

 to two forms. One I propose to name Mas sebastianus, the 

 peculiarity of the fur suggesting arrows sticking in its skin. 

 The other I name Malacomys centraiis ; the examples of this 

 species were collected and presented to the British Museum 

 by Dr. Emin Pasha ten years ago, and referred to by 

 Thomas (P. Z. S. 1888, p. 11) as M. longipes, but have 

 until now never been compared with specimens of M. longipes, 

 M.-Edw. The Museum has since acquired several specimens 

 of this West- African form. 



Mus sebastianus, sp. n. 



Size rather smaller than M. rattus : whole of the upper 

 parts dull coffee-brown, fur soft and rather woolly, inter- 

 spersed with long shining lance-shaped darker hairs ; beneath 

 greyish white, not sharply separated from the colour of the 

 upper parts ; feet and hands covered with fine short adpressed 

 brown hairs ; nails pale horn- colour, small on the fore feet, 

 those on the hind feet much larger and stronger, curved, but 

 not very sharp ; front part of the face and nose thickly 

 haired ; whiskers all black-brown, long, reaching well beyond 

 ears ; in the alcoholic specimens the ear laid forward just 

 reaches to postcanthus of the eye ; tail very long, unicoloured 

 dark slate, smooth and practically naked.
