94 On Far-Euktern Species o/Myospalax. 



throngliout, or periiaps a little broader, this depending; in part 

 on the age of the individuals. Incisors rather less obliquely 

 twisted, more as in other species ; those of the type of 

 fontanieri with an ur.usual degree of slanting along their 

 outer edges. 



External dimensions of type (taken in the flesh) : — 



Head and body 203 mm. ; tail 70; hind foot 35. 



Skulls of adult male and female, the first the type : 

 condylo-basal length 49"8, 485; condylo-incisive length* 

 49-6, 47-9 ; zygomatic breadth 385, 35 ; nasals 19-5 x 8, 

 18x7*2; breadth of anteorbital bridge 2'2, 2"1; interorbital 

 breadth 10"4, 9*1 ; length of masseteric fossa 13'3, 13-2 ; 

 posterior breadth on transverse crests 37, 33 ; palatilar 

 length 25'3, 25 ; palatal foramina 7*7, 7"3 ; upper molar 

 series (alveoli) 12, 11'8.

Type. Adult male. B.M. no. 9.1.1.209. Original 

 number 2001 f. Collected 23rd June, 1908, by M. P. 

 Anderson and A. de C. Sowerby ; presented by H.G. The 

 Duke of Bedford, K.G. Eleven specimens. 



The considerable difference in the structure of the muzzle 

 and anteorbital foramen affords quite sufficient reason for 

 distinguishing the Shan-si mole-rat from that described by 

 Milne-Edwards.

External characters about as in jysilurus. Metapodials 

 thinly hairy, digits naked. A white coronal streak present. 



Skull very like that of psilurus, but with certain constant 

 diffcrtiices. Nasals with their anterior third, after the first 

 slight narrowing, again convex outwards on each side, about 

 as drawn on the left side of Milne-Edwards's figure of the 

 skull of p6i7t<r«s { ; the figure is thus not correct, as in the 

 type the two sides even diverge forwards, both sides being as 

 drawn on the right of the figure. Anteorbital foramen with 

 its outer vail not projected forwards above, or only very 

 slightly in old age, the anterior protilc-line from the shoulder 

 of the zygoma to the muzzle joining the latter praciically 



* An exceedingh' old male, with greatly developed cranial ridges, has 

 a condylo-incisive length of 51 :? mm., but I have not thought it advisable 

 to select so exaggerated a specimen as the type.
