toucli, as stated by M. Milne-EdAvards in the original description. 

 Under parts pure milk-white, sharply contiasted with that of the 

 upper parts. Feet whitish, but the colour of the upper parts 

 runs down the centre of their upper surface to a varying extent. 

 Tail moderately long and bicoloured, clothed with short haiis; its 

 terminal portion is usually, but not invariably white. The skidl 

 is that of a typical Mus of the jerdoni group, being long and 

 narrow, somewhat flattened and with small bulla?. 



Dimensions (in flesh). Head and body 164 mm.; tail 192; 

 hind foot 39 ; ear 18. 



Skull (average dimensions). Gi'eatest length 36 mm. ; basilar 

 length 27-5; palatal length 15; diastema 9*75; incisive fora- 

 mina 6"6 ; length of nasals 13*6; zygomatic breadth 16; inter- 

 orbital breadth 6 ; greatest breadth of brain-case 14 ; length of 

 molar series (alveoli) 6. 



Habitat. The type was received from P6re David 'fiom the 

 mountains of Moupin, in the j)rovince of Szechuen, W. China. 

 There are also specimens in the Museum from E. Kiangsi, from 

 Kuatun and Ching Fen Ling in N.W. Fokien, and from Nankin, 

 all forming a very uniform series showing hardly any variation. 



It is as a rule generally found in the mountainous country, 

 occasionally entering the houses in winter ; and it may be easily 

 recognised, for its dull brown colour and pure tohite under parts, 

 sharply divided from the colour of the back, form a combination 

 of chaiacters found in no other Eat from that part of the world. 



Some of the spiny individuals very closely resemble Jiws nivei- 

 vente?' from the Himalayas, of which it is probably the Chinese 

 representative.

 running down the centre of their upper surface. Under parts 

 pure white, the line of demarcation being sharply defined. Tail 

 rather longer than the head and body, clothed with short hairs 

 and bicoloration. Ears moderately long and sparsely covered 

 with very close, short, dark brown hairs.

 and general appearance, but may be recognised b}^ the supra- 

 orbital ridges being continued right across to the posterior margin 

 of the parietal.
