MiDiinuihs from Monnl Ilawenzori. 145 



Ilah. JiiiwcMizori Kast. Altitiido of type 700;/; other 

 spt'ciiiiciis up to 12,000'. 



Tiji)e. ]\I;iIe. Jj.M. no. 6. 7. 1. 112. Origiiiul nuniher 2IJ5. 

 Collected 15tli .January, I'JOG, by Douglas Cariutlicr.s. Ten 

 specimens. 



This pretty mouse is no doubt allied to Mus Alleni, witli 

 which it shares the general proj)ortions, shaj)e of skull, and 

 number of niamniw; but it differs by its softer, more buffy 

 iur and longer jjalatiiie foramina. In Mus cdrillus, otherwise 

 allied, there are only 1 — 2 = mammaj. 



I have been in some doubt as to whether this or a larger 

 sj)ecies obtained by the Ruwonzori Expedition should be 

 referred to de Winton*s ^f. Jacksoni, founded on a young 

 specimen from Entebbe, but the teelh of the type arc more as 

 in the larger form, and there i.s a distinct projection forward 

 of the zygomatic plate, ])ractically absent in the present form. 



A mouse from Mount Kenya, obtained by Prof. Mackinder 

 in 1899, and referred by me to J\l. Jacksoni^ would also seem 

 to be assignable to Mus JJenm'ce.
