SECOND YARKAND MISSION. 
These measurements would of course be for the most part rather more in fresh sp 
mens. 
The following are the dimensions of a skull : —

The nasal bones are suddenly constricted at rather less than half their 
length from 
front ; thence they continue nearly the same width to the posterior extremity, where they aI 
rounded. The incisors are orange in front, the upper pair sometimes with a very shall 01 * 
groove down the middle. The anterior molar in the upper jaw consists of live prismatic 1°^’ 
and has three salient angles inside and three outside ; the second consists of four lobes '"' l ! 
two angles inside and three outside ; the third of four lobes, the last being irregularly shap e ' 
and turned round at the end so as almost to form a fifth, and with three salient angles* 
hindmost less prominent, inside, and three outside. In the lower jaw the anterior molar h 
four salient angles externally, five internally. The second tooth consisting of five prisms h aS 
three angles on each side, the third tooth consists of three lobes, and has three project^ 011 
inside and two very small on the outside. , 
On one of the labels it is stated that this species lives in holes in grassy places a® 
fields. Stoliczka in his diary mentions finding it in the range north of Kashmir as well ilS 
on the Pankong lake. Mr. Theobald’s original specimens were from tbe Tso-moriri, 1 betW eel1 
Spiti and the Pankong lake, and he noticed its abundance on the shores of the lake where l' 1 
frequently found that its holes “ were ranged in a long line against a bank, and usually c ' v 
tended so far, that all attempts to capture an animal by digging or flooding the holes with 
proved fruitless.” He adds : “ After infinite trouble, however, I managed to dig out an 
ach 1 * 
female, which on examination I found to contain six young ones, the size of liorse-bea 11 j 
three in each horn of the uterus. The total length of this specimen was 615 inches* 0 
which the head was P3, and the tail 1-25 inches. I subsequently got several more, m° s • 
half grown, by watching near their holes with a gun.” 
Of the types procured by Mr. Theobald, one, in spirit, was presented to the Asi £l 
Society’s Museum. This, after some search, has been refound by Mr. Theobald himself* aI1 ’ 
although the label had been lost, satisfactorily and unmistakably identified. Tbe specie 1 ^' 1 ’ 
although considerably smaller than the female mentioned above, proves to be an adult m a 
It is precisely similar to the specimens brought by Dr. Stoliczka from the Pankong lake- 
Dr. Stolickza, too, in his account (J. A. S. B., 1865, xxxiv, p. 110,) of the haff ofll ^ e 
which he identified with L. curzon 'ue, 1 mentions this species as inhabiting the borders of , 
Tso-moriri with the Lcigomys and an Arctomys 3 . He says that the Arvicola (P/m«’ow ^ 
never frequents a great elevation above the bottom of the valleys, and is especially nuD 101 , 
ous in the neighbourhood of streams. He adds that it is found in Spiti and Lahoul* aJl 
even in Kulu.
