On new Japanese Mammals. 487 



LXIII. — On some neio Japanese Mammals presented to the 

 Jh-itish Museum by Mr. R. Gordon Smith. By OlI)FIi:ld 

 Thomas, F.R.S. 



The National Museum owes to the kindness of Mr. R. Gordon 

 Smith an interestin,^," collection of small mammals obtained 

 by him in Japan. The majority are from Kobe, but he has 

 also sent a number collected at Misaki, near Yokohama, by 

 a Jajianese, Mr. H. Tsuchida. 



Most of the species are, of course, described in Tern- 

 miiick and Schlegel's ' Fauna Japonica,^ but the following 

 seem to represent new si)ecies or subspecies, and include a 

 vole which, although allied to the red-backed voles {Evotomys)^ 

 is so distinct that 1 have had to make a new subgenus for it. 

 It forms, therefore, a most interesting discovery. 



Mogera icogura l-ohece, subsp. n. 



Similar in colour and other characters to typical M. loo- 

 gura, but markedly larger. 



Dimensions of the type (measured on a spirit-specimen) : — 



Head and body l4o mm. ; tail 20 ; hind foot, s. u. 21, 

 c. u. 24 ; fore foot, length (c. u.) 26, breadth 20. 



Skull: greatest length 39; basal length 34; greatest 

 breadth 187; front of canine to back of m^ 14' 7 j front of 

 lower cariniform premolar to back of 7>^3 12'8. 



Ilah. Kobe, Hondo. Altitude about 60 m. 



Type. Adult female. B.M. no. 82. 7. 27. 12. Collected 

 2nd June, 1875, during the cruise of H.M.S. ' Challenger.' 

 Five specimens examined. 



While the fine series of the ordinary Japanese mole, M. wo- 

 gura, from Misaki, near Yokohama, sent home by Mr. Gordon 

 Smith are all very uniform in size (skulls 34-35 mm.; hind 

 foot, s, u,, about 18 mm.), the four he has sent from Kobe 

 are all markedly larger, and it is evident that we have here 

 to do with two local forms, though they will probably prove 

 to pass one into another in the intermediate districts. 



In'o t} pical locality is given in Temminck's original 

 description of Tolpa wogura *, but an exam|)le sent in 1843 

 from the Leyden Museum as representing that form agrees in 

 size with the Yokohama race, and I have therefore taken 

 that as the typical one. The original figure of the skull is 

 35 mm. in length.
