Skull. Greatest length 27 mm. ; palatilar length 12 ; diastema 8 ;

breadth 4; breadth of brain-case 11; length of molar series

Habitat. The type comes from near the Corean border of 
Manchuria. The British Museum contains a further specimen 
from S. Shensi procured by Pére David, which has been referred 
to this race. 
MICROMYS AGRARIUS NINGPOENSIS Swinh. 
Mus ningpoensis Swinh. P. Z.8. 1870, p. 637 et 1872, p. 818. 
Mus harti Thos. P. Z. 8. 1898, p. 774. 
Very similar to UW. a. manchuricus, but lacking the rufous 
tinge on the back, which in the present species is replaced by 
fulvous. General colour above fulvous throughout, uniformly 
grizzled with black. In some cases a well-defined dark stripe is 
apparent down the back, and in most specimens a trace of a dark 
stripe is discernible. Under parts white, sharply defined from the 
colour of the upper parts. Tail brown above, lighter below, and 
covered with short hairs. 
The skull does not appreciably differ from that of J. agrariws 
typicus. 
Dimensions (of type converted from inches given in Swinhoe’s 
description). Head and body 81 mm.; tail 68; hind foot 
(measured from type) 20. 
Another example, ¢ (in flesh, coll. E. B. Howell, no. 69). 
Head and body 111 mm.; tail 78; hind foot 20; ear 14. 
Skull. Greatest length 26 mm.; basilar length 21-5; palatilar 
length 11; diastema 7; length of incisive foramina 5 ; length of 
nasals 10; zygomatic breadth 12; interorbital breadth 4°7 ; 
breadth of brain-case 11:5; length of molar series 4. 
Type. Collected by Mr. Swinhoe. Now in the Berlin Museum. 
Habitat. Ningpo. The British Museum contains specimens also 
from Nankin, Hanchow, and Kuatun. 
T have had to sink, under Swinhoe’s name, Mr. Thomas’s dJZus 
harti, as there can be no doubt as to itsidentity with nimgpoensis. 
Since the description of Mus harti was written, a fine series has 
been received from the neighbourhood of Nankin, collected by 
Mr. Howell. It appears that although the dorsal stripe is asa rule 
faint and indistinct, it is in some cases deep black and very well 
marked, while in other individuals no trace of it can be found. 
Herr Matschie (in litt.) states that in the type of ningpoensis 
there is no trace of the dorsal stripe, and the same is the case 
with the type of J. harta. 
Little is known of its habits; Mr. Howell seems to have 
trapped most of his specimens on open ground in the vicinity of 
water.
