228 MICROTIN^ 



Characters.- — Like E. g. nageri, but with slightly smaller skull 

 (condylo-basal length 24-25, instead of 25-26-2 mm.). 



Colour of back cinnamon-rufous ; face, cheeks, flanks and rump 

 clear brown ; under parts whitish or light greyish with a weak 

 suffusion of yellowish-brown. Dorsal colour somewhat variable, 

 ranging from the dark hues of the young and some adults through 

 cinnamon-rufous, rust-red, to a pale yellowish red in some in- 

 dividuals. Line of demarcation usually distinct; much less 

 evident in young and some adults. Feet whitish, sometimes clear 

 and silvery, sometimes darkened. Tail above more or less deep 

 brown, below white, whitish or light brown. Colour darker in 

 summer than in winter; and in young than in adults. 



Height ajiparcntly without influence on colour ; an individual 

 from 2545 m. like those from 1000 m. 



Skull and teeth slightly but constantly smaller than in E. g. 

 nageri; m^ usually with a well-developed third inner infold 

 (87% of the individuals). 



For external and cranial measurements, see tables at end of 

 volume. 



Remarks.- — In size the skull is nearly as in E. g. istericus, the 

 form inhabiting the Danube Basin ; but in colour, size of hind- 

 foot, and in the structure of the m^ the present form shows itself 

 to be more nearly related to E. g. nageri, from which, judging by 

 specimens sent by Signor Dal Piaz, it is scarcely distinguishable 

 externally. 



5c. Evotomys nageri vesanus subsp. n. 



Type.—E.W., No. 8.11.30.12; adult female, collected 

 August 20, 1907, by Dr. C. I. Forsyth Major. 



Tyj^e locality.- — Mittelberg, near Kaufbeuern, Bavaria, 

 Altitude 1200—1300 metres. 



Range.- — Known only from the mountains in the neighbour- 

 hood of Kaufbeuern, Bavaria at elevations between 4000 and 

 6000 feet. 



Characters. — External appearance as in E. n. nageri, but 

 possibly a trifle smaller (hind-foot in three specimens 18 mm.). 

 Skull about as long as in E. n. nageri, but relatively narrower 

 throughout. Cheek-teeth smaller and lighter; m^ without a 

 third inner infold or fourth inner salient angle. 



For external and cranial measurements, see tables at end of 

 volume. 



Remarks. — The cranial peculiarities of this outlying repre- 

 sentative of the Alpine E. nageri prevent me from referring it to 

 either the typical form or to Dal Piaz's recently described E. n. 

 italicus.
