Tyjyp local! tji. — Hun gaiy . 



Geographical didrihntion. — Hungary ; Denmark ; * south- 

 eastern Norway.f Details of distribution ver\' imperfectly 

 known. 



Diai/iwsis. — Least depth of rostrum behind incisors decidedly 

 greater than breadth of rostrum in same region ; crown area of 

 m^ about three times that of premolar : sides essentially concolor 

 with back. 



Colour. — Back, sides and head uniform raw-umber with a 

 slight buify tinge, this more noticeable on cheeks and sides of 

 neck than elsewhere ; back veiy inconspicviously " lined " with 

 black. The individual hairs of the underfur are slate-colour at 

 base (5 mm.), the tips (1 -5 mm.) bufly raw-umber ; longer hairs 

 (12 mm.) black, the tips (2 mm.) colourless and with a silvery 

 gloss. Median dorsal line with clear black stripe aboiri 3 mm. 

 wide, extending from crown to base of tail, better defined 

 posteriorly (except within a few mm. of base of tail) than 

 anteriorly, but not thrown into relief by lightening of background 

 along any part of its extent. Underparts light oc.hraceous-buff 

 without line of demarcation along sides, much dulled by 

 appearance at surface of slaty under colour. Ears essentially 

 concolor with back, but with a stronger admixture of black, the 

 rim clear light buffy. Feet a light indefinite buffy brown rather 

 paler than belly, the toes still paler. Tail obscurely bicolor, 

 sepia above, dull cream-buft' below.
