XLIV. — Descriptions of Tico new Muridiy from Central 

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



The examination of some specimens of We.st-AtVican Muri.Ue 

 lately acquired by the British Mnsenm and kindly entrusted 

 to nie for determination by Mr. Oldiield Thomas shows the 

 necessity for descriptions being drawn out and names given 

 to two lorms. One 1 propose to name Mas subastianus, the 

 peculiarity of the iur suggesting arrows stieking in its stin. 

 The other I name Malacomys centralis ; 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. II) as M. lomjip/^s, but have 

 until now never been compared with s|)ecimens of M. lonf/ipes, 

 M.-Edw. 1 he Museum has since acquired several specimens 

 of this West- African form. 



Mus sebastianus, sp. n.

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

 spersed with long shining lance-shaped darker hairs; beneath

 upper parts ; feet and hands covered with fine short adpressed
