This species may be distinguished from M. delicaiulus by its 

 larger and from M. forresti by its smaller size, and from M. 

 Aermcmnsburgensis by its comparatively small bullae. M. novce- 

 hoUandice Waterh., which is somewhat similar externally, is not 

 a member of this group, having normal molars without supple- 

 mentary anterior cusps. 



Mr. Stalker states that he dug these mice out of holes, in each 

 of which he found one male and two females.
