222 MICROTIN^ 



Type.—BM., No. 4.4.6.72; adult male, skin and skull; 

 collected by W. Dodson ; presented by Lord Lilford. 



Type locality, — Bustenari, Prahova, Rumania (in the Car- 

 pathians, north-west of Bucharest). Altitude 480 m. 



Range. — Drainage basin of the Danube, from Bavaria through 

 Hungary to Rumania and probably to Bulgaria and the coast 

 of the Black Sea. 



Characters. — Distinguished from other subspecies by its rather 

 narrow, lighter, yellowish-rufous mantle ; and by the form of 

 its auditory bullae which are more abruptly inflated on the inner 

 side than in E. g. glareolus. 



Summer pelage : dorsal stripe narrow and well defined, not 

 tending to spread over sides. It is rufous slightly varied with 

 yellowish wood-brown, and rather thickly sprinkled with black- 

 tipped hairs. Face, cheeks, and sides pale yellowish wood- 

 brown, tinged with grey : rump like sides, rather strongly con- 

 trasted with mantle. Under parts varying from creamy white to 

 a yellowish cream-buff. Feet greyish white. Ears thinly haired, 

 concolorous with mantle. Tail sharply bicoloured, brown above, 

 soiled white below. 



Winter pelage : mantle slightly less sharply defined than in 

 summer, the rufous paler but warmer, considerably varied with 

 wood-brown, but very inconspicuously sprinkled with black- 

 tip23ed hairs. Face, cheek and sides more yellowish wood-brown 

 than in summer, and scarcely tinged with grey. Rump slightly 

 suffused with colour of dorsal area, and therefore less contrasted 

 with back than in summer. Feet nearly pure white. 



Skull like that of E. g. glareolus, but with larger auditory 

 bullae ; inner margins of bullae more nearly approaching each other, 

 and rising more abruptly above level of basioccipital. Cheek- 

 teeth normal ; m^ with third inner infold present in about 64% of 

 the skulls examined. 



For external and cranial measurements, see tables at end of 

 volume. 



Remarks.- — This is the brightest-coloured and best-marked 

 subspecies of E. glareolus known.
