EVOTOMYS 223 



Range. — -Jura Mountains ; southwards through the non- 

 Alpine parts of Switzerland and along the lower western portion 

 of the French Alps. 



Characters. — Size rather large (hind-foot 17-19 mm. ; condylo- 

 basal length of skull 23-24-5 or 254 mm); colour somewhat 

 paler and more buffy-greyish than in either E. g. glareolus or 

 E. nageri. Skull rather strongly built ; m^, in about two-thirds 

 of the specimens examined, with a third inner infold. 



For external and cranial measurements, see tables at end of 

 volume. 



Remarks. — Of eleven adult skulls, ten, including the type and a 

 good series from Cranves-Sales, Haute-Savoie, have the condylo- 

 basal length ranging between 23-1 and 24-5, wh le in form they are 

 strictly of the E. glareolus type. One skull from Cranves-Sales 

 (B.M., No. 5.11.18.43?) is much larger (its condylo-basal length 

 25-4 mm.) and in form it agrees very closely with E. nageri. I 

 can detect no difference between the skm of this si^ecimen and 

 those of the others from the same locality; but it is possible that 

 both E. glareolus and E. nageri are represented at Cranves-Sales. 

 Apart from the specimen referred to, I can see no evidence of 

 E. g. hr.lreticus being in any way intermediate between the two 

 species, and it seems to me to be a rather well-marked race of E. 

 glareolus.

Type.~B.M., No. 21.12.1.16; adult female, collected Sep- 

 tember 13, 1921, by E. and V. Martino. 



Type locality. — -Rescetari, Nova Gradisca, Croatia. 



Range. — Known only from the type locality. 



Characters. — Size rather large (hind-foot 18 mm., condylo- 

 basal length of skull 24-4 mm.). Tail relatively short, about 

 46% of head and body measurement. 



Dorsal colour duller and more drab than in E. g. helveticus. 

 Tail pale dust-colour above, instead of dark brown or dusky as in 

 other forms, yellow-buff below. 



Skull most like that of E. g. helveticus, but with slightly larger 

 and more vaulted braincase. Cheek-teeth normal; m^ with 

 three weU-developed salient angles on each side and with weak 

 vestiges of the fourth inner and outer angles in younger stages of 

 wear. 



For external and skull dimensions, see tables at end of 

 volume. 



Remarks. — The peculiarly short and pale tail satisfactorily 

 distinguishes this form from other races of E. glareolus.
