from Pinanj^, Bunguran (typical of natunce, Miller), and 

 North Borneo. On the other hand, the Malay specimens 

 vary immensely among themselves, sometimes even when 

 coming from the same locality. 



In this connection it is to be noted that while most of 

 ^Ir. Miller's insular species of mammals have been founded 

 on fine series of specimens, those of Galenpterus have, with 

 one exception, been based on either one or two examples, and 

 therefore he has hardly had sufficient material to test the 

 cranial variability of these animals. 



XL. — Three new African Species o/"Mus. 

 ]3y R. C. Wroughton. 



The recent receipt by the Natural History Museum of a 

 collection (Rudd Exploration) from Tette containing speci- 

 mens of the multimammate group of mice, and thus fixing 

 Peters's Mus microdon^ of which they are the topotypes, led 

 me to examine all the individuals representing this group in 

 the Museum Collection. The species of this group extend 

 almost all over Africa, filling the place which Micromys 

 occupies in Europe. The National Collection possesses fine 

 series from many localities, but nevertheless insufficient to 

 justify a monograph of the whole group ; two forms, however, 

 which came under ray notice are sufficiently distinct to be 

 worthy of description. 



Mus huberti, sp. n. 



A multimammate mouse rather larger than M. erythro- 

 leucus and of a paler colour. 



Fur rather short, 7-8 mm. long on the back. 



General colour above near "wood-brown," below pale 

 grey. Individual hairs of the upper surface pale slate-grey 

 basally, tipped with black, and with a subterminal pale buff 

 ring ; of under surface pale grey basally, white at the point. 

 Chin, hands, and feet white. 



Skull markedly larger than in M. erythroleucus. 



Dimensions : — 



Head and body (circ.) 135 mm.; tail (circ.) 135; hind 

 foot 27; ear 19. 



Skull : greatest length 32 ; zygomatic breadth 16 ; 

 diastema 9 ; upper molar scries -i'O.
