220 MICROTIN^ 



sprinkled with longer black hairs. Flanks, cheeks, and face 

 before the eyes are lighter ; the flanks greyer and less buffy than 

 in the tyjjical form. There is no distinct line of demarcation. 

 Underside whitish, frequently washed to a variable extent with 

 yellowish or buff. Feet greyish. Tail distinctly though often 

 inconspicuously bicoloured. The colours are lighter red when 

 faded, as in late winter. 



Moult.— A. coarser coat is assumed in October, after which in 

 cold localities the flanks may be greyer. A moult has also been 

 observed in early May. 



Young specimens have less brightly coloured backs. In the 

 woolly Juvenal coat the underside is at first dusky; later, as 

 longer hairs with light tips increase in number, the characteristic 

 tints of the adult are gradually assumed, at first on the upper 

 surface. A buff or yellowish belly, when present, is character- 

 istic of the adult pelage, and is most conspicuous in winter 

 siiecimens. 



Skull like that of E. g. glareolus, but slightly smaller in average 

 size ; m^ usually with three salient angles and two infolds on each 

 side; a third inner infold and a fourth inner salient angle are 

 usually present, however, in the m^ of young and subadult in- 

 dividuals ; according to Miller the third inner fold is present in 

 about 25% of the individuals examined, but I find recognizable 

 traces of this fold in at least 50% of the specimens before me. 



For external and cranial measurements, see tables at end of 

 volume.

Type locality. — Hapsal, Esthohia " In Obst- und gemiise- 

 garten." 



Range. — Esthonia. 



Characters. — Most like E. g. suecicus in general character, but 

 colour much darker. 



Upper parts clothed with a fine mixture of dark reddish- 

 brown and dusky hair-tips, the general effect produced, where j 

 brightest (as between ears and on nape), being no brighter than the I 

 " chestnut " of Ridgway ; darkest on rump, where the elimination ! 

 of rufous hair-tips leaves the colour dark slaty-grey. Rufous : 

 tinge traceable far back towards rump and far down flanks. 

 Under parts silvery grey, much darkened by the slaty bases of , 

 the hairs. Ears dusky. Tail dusky above ; its lower surface, 

 together with the hands and feet, dirty white. 



Skull similar to that of E. g. suecicus in size and general appear- j 

 ance ; zygomatic arches slightly less expanded ; bullae slightly I
