SAND MOLE 99 



Sub-family CRICETIN^. 

 Genus MYSTROMYS. 



Fur soft and woolly. Ears large and broad. Tail short. 



The White-tailed Mouse {Mystromys albipes ~ alhi- 

 caudatus) is brownish grey above and paler below, the 

 tail, feet, nose, and chin being white. Body plump, 

 hence its name of "Fat Mouse" sometimes used by 

 authors. The Zoo possessed a pair from a cave near 

 Krugersdorp, presented by Dr. H. Lyster Jameson, 

 which bred freely and reared a number of litters. Four 

 appeared to be the usual number, and the young hung 

 on to their mother's teats while she stalked about in a 

 most unconcerned manner.
