Type. — Perhaps in Leningrad (not seen by Mr. Montagu) ; a 

 specimen in alcohol collected in the summer of 1857. 



Type locality. — Eastern Syansk Mountains. 



Characters. — Radde's careful description of the external 

 characters of bis specimen leaves no room for doubting that his 

 Arvicola (Hypudceus) nissatus is based upon E. rutilus ; and the 

 measurements (total length 86 mm.; bead and body 63 mm.; 

 tail 24 mm. ; bind-foot with claws 17) indicate that the specimen 

 was immature. The description does not, however, reveal any 

 character by which this form can be satisfactorily distinguished 

 from E. r. rutilus. The supposed differences in the m^ described 

 by Radde are, in my opinion, imaginary; the last molars have 

 apparently fallen out of their alveoli and have been replaced in 

 a reversed position. 



Mr. G. M. Allen has lately referred to this form a large series 

 of specimens collected by the American Museum Asiatic Expedi- 

 tions " in the wooded country five miles northeast of IJrga, 

 Mongolia. . . . These differ from a series from the Altai referred 

 to rutilus in their slightly brighter colours and in having the 

 tails usually more or less reddish like the back instead of blackish 

 as in these latter. Although no specimens of rutilus from the 

 Obi region are available as topotypes, it is assumed that the 

 Altai specimens are the same, and I have therefore applied 

 Radde's name to the Mongolian series."
