The '(!)hallengcr ^ also obtained three specimens of (rue 

 tvogura from Yokohama, besides the example of M. iv. kohece 

 which 1 have selected as tiie type. 



Although much larger than true M. rcogura, this mole falls 

 far short of the large form from Vladivostok named by 

 Dr. Nehring M. robusta *. 



Petaurista Jeucogenys and its subspecies. 



Mr. Gordon Smith has sent several specimens of the large 

 Japanese flying-squirrel, and I have carefully examined these 

 and the specimens already in the Museum collection. 



The original locality of Temminck's Pteromys leucogenys 

 was the mountains of Figo ( = Higo) and Fiuga, in the island 

 of Kiusiu, so that specimens sent from Nagasaki, in the 

 same island, may be provisionally treated as typical. 



These are very dark above, with their under surface white 

 or neaily white, not or scarcely washed with buffy, their lips 

 with but little greyish white on them, a well-marked blackish 

 patch below the eye and another below the ear, the charac- 

 teristic light cheek-patch greyish and not sharply contrasted. 



From this Kiusiu animal there may be distinguished the 

 Ibllowing three subspecies: — 



P. I. nikkom'Sf subsp. n. 



Fur particularly long and tail bushy. General colour 

 ])aler, more greyish brown or drab. Under surface white. 

 Muzzle whitish. Below eye greyish brown. Light cheek- 

 patches snowy white, very prominent. 



NikkOj central mountainous region of Hondo. 



P. 1. oreas, subsp. n. 



Colour above rich brown, warmer than in the Kiusiu form, 

 and suffused with rufous on the head. Under surface washed 

 M'ith buffy. Patch below eye dark rufous, like forehead. 

 Light cheek-patch dull greyish, inconspicuous, washed with 

 buffy. 



\Vakayama, southern peninsula of Hondo. 



P. I. toscv, subsp. n. 



Colour above an intermediate brown. Hairs of under 

 sn)face slaty at base, washed Avith bufly terminallj'. Lips
