I can find no characters to warrant recognition of the form 

 described from Mount Kenia by Heller as Mus gratus sungarse. 



A grass mouse, usually entirely away from bushes and trees. Usually taken in 

 the runways of the larger species. Occasionally come into tents. Nocturnal. 

 (Appendix B, p. 477.) Caught in traps set at random in the bushy thickets in the 

 lowland, as well as in the open grassy spots on the rocky hillsides where they fre- 

 quented the runways made by various species of Mus. A few were collected 

 on Mount Kenia. (Appendix C, p. 484.)^
