332 A memoir on the Rats and Mice of India. [ No, 4, 
“Mus (?) macropus, H. A Water-Rat like the last, but twice as large. Dis- 
tinguished by the largeness of its feet, and also by the fine pelage and the 
proportions of the last, as well as by a similar bluff face, though less so than 
in M. (2?) pyctoris. Above smoky black, below smoky-grey. Legs dark, toes 
pale. Snout to rump 7% in.; tail 6 in,; head 2,4 in.; ears 1, in.; palma plus 
1 in. ; planta 123 in. ; weight 6 oz.” (Hodgson.) 
In J. A. S. XV., 139, I referred a species from the extreme V. W. 
of India and Afghanstan, to this Mesokia group by the name Mus 
Huttoni, nobis; and Mr. F. Moore has since described a Wesokia 
Griffithii, Horsfield, from Afghanstén, in the Catalogue of the 
Indian-House specimens of mammalia, which is probably the same 
animal, notwithstanding certain discrepancies in the descriptions. 
N. Hurroni, nobis—“ Bears a near resemblance to M. 1npica (vy. kok), but 
the tail is shorter and the general colour much lighter, resembling that of the 
Gerbilles. On comparison of the skulls, the Zygomatic arch is seen to be con- 
spicuously broader anteriorly ; and the palate is much narrower, and contracted 
to the front: but the most obvious distinction consists in all the teeth, both 
incisive tusks and grinders, being considerably broader and stronger. In other 
respects, the skulls of these two species bear a very close resemblance. Leneth, 
minus the tail, about 6 in,; the tail, (vertebre,) 4 in.: tarsus with toes and 
claws, 1? in.; ears posteriorly 4 in.; to anteal base in. Fur soft and fine, 
blackish for the larger basal half of the piles—the surface pale rufescent-brown, 
deepest along the crown and back, pale below, and whitish on the throat ; 
whiskers small and fine, and chiefly black; tail naked; feet light-brown: 
incisive tusks buff-coloured ; the enamel of these has been partially worn away 
on those of the upper jaw.’ (B1.) 
This animal ‘“ occurs south of Bwhawulpore, and is abundant in Afehanstan, 
from Quetta to Girishk, throwing up the mould after the manner of the mole, 
It feeds on herbs and seed, and burrows in the ground beneath hedge-rows and 
bushes, as well as along the banks and ditches. Its nest is deep-seated, and it 
constructs so many false galleries immediately below the surface, that it is difficult 
to find the true passage to its retreat, which dips down suddenly from about the 
middle of the labyrinth above. In the gardens and along the sides of water- 
courses in the fields at Kandahar, their earth-heaps are abundant.” (Hutton.) 
Nesoxia Grirrirait, Horsfield “ Fur very soft and silky : colour above, dusky 
chesnut-brown with streaks of a plumbeous tint, the separated hairs being of a 
leaden-colour at the base, and chesnut-brown towards the extremity ; chin, 
chest, and under parts of a lighter tint, passing into a greyish-leaden colour on 
ears moderate, rounded ; whiskers black at the base, slender, weak; front cut- 
ting teeth broad, yellow; grinders very large, much}larger than in Mus bandi- 
cota. Hind-foot 1 in. 8 lin. ; skull to back of palate 1 in. 1% lin. ; grinders 45 lines 
Jong and 2 lines wide.” (Gray).
