236 MICROTIN^ 



Type locality. — Sumela, about 30 miles south of Trebizond,. 

 Asia Minor. 



Range. — Forest region south of Trebizond. 



Characters. — Size large (hind-foot 19 mm. ; condylo-basa 

 length of skull 24'6 mm.) as in E. nageri, which it resembles in* 

 general colour. Distinguished from E. nageri by its greyer rump 

 and sides, buffy-washed belly, and darker hands and feet. Tail 

 heavily haired, black above and at the end, dull creamy below. 



Skull large, remarkably smooth and rounded ; the braincase 

 long and narrow, less ridged and angular than in allied forms. 

 Temporal ridges in the interorbital region weak and marginal; 

 surface of frontals nearly j)lane, instead of bearing a shallow 

 median sulcus as in most other species; dorsal profile evenly 

 and smoothly convex. Zygomatic arches less expanded than in 

 E. nageri; jugals very light. Anterior palatal foramina well 

 open behind. 



Cheek-teeth normal in pattern, but very light; m^ with a 

 well-develoj)ed third inner infold and a rather small fourth inner 

 salient angle ; third outer infold of this tooth usually shallow and 

 sometimes obsolete, there being no trace of a fourth outer salient 

 angle. 



For external and cranial measurements, see tables at end of 

 volume. 



Remarhs. — Ajjparently more closely related to E. nageri than 

 to other s^^ecies.

Characters. — Size medium (hind-foot 19 mm. ; condylo-basal

 brown. 



Fur soft, loose, not so long as in E. centralis, the hairs of the

 length, longer than in E. centralis and not so heavily haired as
