p. 198, February, 1908. Type in British Museum.

Type locality. — Transylvania (probably near Hatszeg, Hun- 

 yad, Hungary). 



Geograjjhical distribution. — Known only from the type locality. 



Diagnosis. — A large member of the Microtus arvalis group, 

 about equal to the Grecian M. hartingi in size, but with much 

 longer tail ; skull with unusually deep rostrum and abruptly 

 sloping nasals. 



Colour. — After about thirty years immersion in alcohol the 

 type appears to be essentially like Microtus arvalis arvalis in 

 colour. 



Shill and teeth. — The skull differs from that of all other 



known European species of Microtus in the very deep, relatively 



short rostrum (depth at back of nasal decidedly greater than 



distance between front of zygoma and anterior extremity of 



nasal) and the unusually conspicuous angle 



r^Cr /TN. (about 34° instead of about 18° to 22° as in 



r^K\ X^07 N ^' ^^^^^'^) -^- hartingi and M. orcadensis) 



K^^-XxxcDSiiff *^^u ^^ which the nasals slope downward. 



t/ Auditory bullae relatively larger than in 



Fig. 145. jf arvalis, but not so much inflated as 



Nat. size. m M. hartingi. Jjorni or brani-case not 



known. Teeth with pattern of enamel 



folding as in Microtus arvalis, but all of the triangles, especially 



those in lower molars, with transverse diameter noticeably 



increased relatively to antero-posterior diameter, and area of 



dentine spaces reduced. 



Measurements. — ^Type (adult male, in spirit) : head and body, 

 115 ; tail, 41 ; hind foot, 18 ; ear from meatus, 12. For cranial 

 measurements see Table opposite. 



Specimen examined. — The type.
