which appear to be undescribed; also Sorex Gtriffithii, Horsfield 

 (erroneously assigned by that gentleman to Afghanistan • being identical 

 with the supposed S. murinus apud nos, p. 28 ante ,- and the true S. 

 murinus having now been presented to our museum from the Tenasserim 

 valley by Mr. Theobald) :— of reptiles, Argyrophis braminus, Dryinus 

 prasinus, and the young of the fine Coluber nigromarginatus, nobis 

 (J. A. S. XXIII, 290), a species previously received only from the vici- 

 nity of Darjiling. 



The three species of Mice from Cherra may be thus characterized. 



Mus gliroides, nobis, n. s. This has very much the aspect of the 

 British Dormouse (Myoxus avellanarius ;) but what little remains of 

 the tail of the only specimen sent is nude, and the colouring is much less 

 bright, though inclining to the same hue. It would seem to represent a 

 very distinct division of the great genus Mus ; but the specimen is evi- 

 dently young, and more and better examples are needed for a satisfactory 

 examination. Fur exceedingly dense and fine, nearly f in. long upon 

 the back, and of a light brown colour tinged with fawn externally, the 

 piles dusky-ash for the basal two-thirds or more : lower-parts white, very 

 faintly tinged with fawn ; the white purest about the lips and chin : 

 whiskers long, copious and fine (like those of Myoxus avellanarius) : 

 feet large, and clad scantily with white hairs ; but a distinct dark brown 

 mark upon each hind-foot, reaching almost to the division of the toes : 

 ears rather small, ovoid and naked. Length of head and body 2 in. ; tail 

 ? ; ears posteriorly -^ in. ; and tarse f in. 



M. erythrotis, nobis, n. s. Another and very different form of Mouse 

 from the last, and equally from the common house Mouse. Length of 

 head and body 2|- in. ; tail 2f in., and consisting of about 26 vertebrae : 

 ears small and hairy, 5 r in. long externally : hind-foot and claws \^ in 

 Fur long and very dense ; of a rich dark brown colour, grizzled, and 

 brightly tinged with rufous or rufo-ferruginous towards the tail and upon 

 the ears conspicuously : lower-parts albescent, tinged with fawn : feet with 

 brown hairs upon their upper surface ; and the tail considerably hirsute. 

 One specimen only received. 



M. cunicularis, nobis, n. s. A small field (?) Mouse remarkable for 

 its ample ears, and tail shorter than the head and body. Length of head 

 and body 2>\ in. ; of tail 2^ in. ; ears posteriorly \ in. ; and hind-foot {% 

 in. Colour of a wild Rabbit (Lepus cuniculus) above, below white ; 

 and the feet with brownish hairs above, but with white hairs upon the 

 toes : tail conspicuously ringed, the setso minute and inconspicuous. A 

 dozen specimens are sent of this species, some of which are more or 

 less injured.
