1870. | MR. R. SWINHOE ON CHINESE MAMMALS. 635 
breast and streak down the centre of the belly white. Length from 
snout to root of tail 20 inches; tail 15, soft and bushy. The red 
fur of the body is sparsely sprinkled with white hairs. The fur is 
soft, moderately long, and much in character with that of Pt. gran- 
dis ; in some lights it shows very brown. 
A specimen of this fine species was brought to me at Takow, S.W. 
Formosa, in December 1865. It seems confined to the southern 
mountains of Formosa.

I have never observed the Bandicoot in China; but in Formosa, 
on the high road from Takow to the city of Taiwan, it was very 
abundant, living in holes at the foot of the hedges that line the way. 
I have not seen them in the towns. It would appear likely that 
this Rat was introduced into Formosa when the Dutch were in pos- 
session, in A.D. 1630. 
T have the skin and skull of an adult from Formosa; the former 
measures from snout to root of tail 11°5 inches, tail 6°75; ear 1:1 
in length. The skull agrees with specimens from India. 
97. Mus pEcuMANUsS, Pall. (Commercial Rat.) 
Mus decumanus, Swinhoe, P. Z.8. 1864, p. 382. 
Abundant in all large towns in South China and Formosa. 
The white and pied varieties of Mus rattus, L., are to be seen in 
cages in the towns; but these are imported. 
58. Mus 1npicvus, Geoffroy. (Indian Rat.) 
Arvicola indica, Gray ; Hardwicke, Il. Ind. Zool. i. t. 11. 
My largest specimen from Formosa is 10°75 in length, tail imper- 
fect, ear ‘66. A smaller one, length 7, tail 5°25. Colour above 
light chestnut-brown ; most of the hairs broadly tipped with black, 
giving in the adult a streaky appearance to the back. Long fine 
moustaches on muzzle white, short ones black. Sides of muzzle, 
feet, and underparts dingy white, with a tinge of yellow. Tail 
sparsely covered with short spinous bristles, brown on the upper, 
white on the under surface of the tail. 
In the city of Taiwan, Formosa, this large Rat was nearly as 
common as the Commercial Rat, and seemed to associate with it. 
I have not noticed it in the towns of the Chinese main. 
59. Mus aALexanprinvus, Geoffroy. (South-European Rat.) 
Adult male measures 8°6, tail 6, ear *7. This species is a good 
deal like the ordinary grey Rat, but has longer and richer- coloured 
pile, the ear is larger and more oval, the feet smaller, and the tail 
proportionately longer, and with much more short hair, especially 
near the tip. Upper parts dark yellowish brown, with many of the
