backward so that its length is slightly more than double its 

 greatest width. Mammae : p 2-2, i 2-2 = 8. 



Colour. — Back a peculiar light brown perhaps best described 

 as a bufty, greyish isabella-colour, tinged with ecru drab on sides 

 of neck, and everywhere .slightly clouded (not "lined") with 

 black. Median dorsal region with a sharply defined black stripe 

 about 2 mm. wide thrown into relief posteriorly by a distinct 

 lightening of ground colour along its edges. Sides ochraceous- 

 buff, not strongly contrasted with back, but distinctly more 

 yellow and with rather sharply-drawn line of demarcation ; 

 below the colour of sides passes insensibly into the lighter, less 

 yellow ochraceous-buff of belly. Ear black sprinkled with bufty 

 hairs and with a narrow l>urty edge. They are rather strongly 

 contrasted with surrounding parts, this effect heightened by the 

 presence of an ill-defined though evident patch behind ear. 

 Feet a light indefinite bufty brown rather lighter than belly, the 

 toes a little more pallid. Tail obscurely bicolor, sepia above, 

 dull cream-buft' below. Longer hairs oi back black to extreme 

 tip ; basal colour everywhere slaty.

merely in the somewhat more .slender rostrum ; least depth 

 behind incisors about equal to width in same region. Teeth as 

 in the related species, but discrepancy in size between premolar 

 and first molar more pronounced, the crown area or the smaller 

 tooth about one-fourth that of the larger. 



Measuremeiifs. — Three adult females from Malcoci, Dobrudscha 

 (in alcohol) : head and body, 55, 56 and 58 ; tail, 69, 75 and 76 ;
