The presence of only four mammae in this mouse is a very curious fact, as there 

 are six in all the other members of the T. doliclmrus group, even in those from 

 comparatively adjacent localities. Specimens from Shoa {Zaphiro), Mt. Elgon {Jackson), 

 Nyasa [Johnston), Angola (Ansorge), and South Africa all possess the larger 

 number. 



[A few of these Mice were trapped in the grass-country belov? the forest. A nest 

 built in the grass some way off the ground was thought to belong to this species, but 

 we failed to obtain the actual owner. — E. B. W.]
