badly broken, these are the only characters that can be set forth as 

 distmguishing these two kinds. 



Sieatoinys thomasi differs from Sfeatomys gazellae in hghter color, 

 smaller body-size and markedly smaller skull. 



From Steatomys athi, Steafomys thomasi may be distinguished by its 

 generally smaller size and somewhat lighter color. The skull is 

 markedly smaller in all respects. 



Remarks: The northern species of Skatomys are badl}" in need of 

 revision. It is quite probable that the species aquilo, gazellae, athi, 

 and thomasi ai'e merely subspecies of the same species, but, until more 

 specimens of aquilo and gazellae are known and intermediate areas 

 collected, I feel it is better to record these names as species.
