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.) nitidalus* Pall., but may be readily 
distinguished by the rather more complicated pattern of its teeth, 
its small bulls, 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. |

those of the European Jus spicilegus. Head and body 92 mm. ;

* Better known as dryas Schr. The peculiarities of this species, which, while 
essentially an EHliomys, shows certain leanings towards Glis, demand a special sub- 
generic name. Hlius Schulze is not available, being a synonym of Gis.
