decumanus, with the under-parts subdued white tolerably well defined. 

 Of the same subgroup as M. musculus and M. Manei. 



M. concolor, nobis, n. s. A house Mouse probably, of an uniform 

 dark greyish i mouse-colour' above and below; eyes of medium size, and 

 ear-conch moderately ample ; feet large, and the tail with close rings of 

 minute setse throughout. Length 3 in., of tail 4 in., and hind-foot •§■ in. 

 From the large proportional size of the limbs, it is probably not full- 

 grown. 



M. badius, nobis, n. s. Like M. oleraceus, Sykes, but the eye fully 

 twice as large, and black whiskers ; colour of the upper-parts a more 

 rufous cliesnut or cinnamon hue ; of the lower-parts white almost pure. 

 Length of a female 3 in. to base of tail, the tail 4f in., and hind-foot f in. 



M. peguensis, nobis, n. s. A field Mouse, with tail longer than the 

 head and body, well clad with hairs that become longer to the end. 

 Length to base of tail 31 in., of tail 3f in. ; ear-conch \ in. ; and hind- 

 foot f in. These are the measurements of a female in spirit. A stuffed 

 male has the tail (vertebrse) Ah, in. Fur very full and dense, pale yellow- 

 ish-brown on the upper-parts, slightly yellowish white below : whiskers 

 remarkably long.* 



* Some other Mice in spirit have been sent by Major Tytler for identification. 

 They are as follow : 



Mus niviventer, Hodgson, Ann. Mag. N. H. XV. (1845), p. 267. A well 

 marked species, rather larger than as originally described. A male measuring 

 6 in. long, with tail 7 in. ; and hind-foot nearly 1| in. : female even larger, or 7 

 in. long, with tail 7| in. From Masuri. 



M. oleraceus, Sykes : Syn. ? M. (Vandileuria) dumeticola, Hodgson, ibid. 

 p. 268. I cannot perceive in what these differ. A specimen from Asam is very 

 slightly deeper-coloured, but I can detect no further difference. A Deyra doon 

 example measures 2| in. long, with tail 4| in. 



M. homottrus, Hodgson, ibid. p. 268. Accords with the description, except 

 that the largest of several specimens does not quite come up to the dimensions 

 stated. The males measure 3J in. to base of tail, and tail the same (having 

 about 24 vertebra?) ; hind-foot plus f in. I have been unable to satisfy myself 

 of the number of teats. Mr. Hodgson states — " It has eight teats only in the 

 females. The other Mice have ten, and the Rats have twelve." As compared 

 with the European M. musculus, the fur is much more Gerbille-like in charac- 

 ter, the piles less dense and sinuous. 



M. CRASSirES, nobis, n. .?. Like the preceding, but with the tail rather longer 

 than the head and body. Length 2f in. ; tail 3j in. ; hind-foot f in. The feet 

 particularly large, and, like the tail, well furnished with coarse short seta). From 

 Masuri.
