348 MR. OLDFIELD THOMAS ON [NoV. 28, 



cannot be assigned to any of the existing groups and must have 

 a special name of its own. It is no doubt most nearly allied to 

 Eliomys {Dryomys, subg. n.) Qiitidulus*' Pall., but may be readily 

 distinguished by the rather more complicated pattern of its teeth, 

 its small bullae, the absence of the angular foramen in its mandible, 

 and its peculiar and characteristic colour- pattern. These characters 

 are all brought out in Reuvens's descriptions and figures, and do 

 not need further reference here.]

* Bettei- known as dri/as Schr. The peculiarities of this species, which, while 

 esseutiallj' an Eliomys, shows certain leanings towards Glis, demand a special sub- 

 generic name. JSlius Scliulze is not a\'ailable, being a sjnionj'm of Glis.
