investigating the matter, and we must await his decision, but from such 
external observations as I have been able to make, it appears probable 
that the following will prove identical : 
Mus homourus; Mus Darzeelingensis; Mus Tytleri; Mus Bactri- 
anus ; Mus cervicolor (?)—Jerdon’s Nos. 187, 189, 190, 191, and 192. 
These are all hill mice, except the last, and found under the same 
conditions. 
No. 356. Mus HOMOURUS. 
Hasirat.—Lower Himalayan range. 
DEsCRIPTION.—Dark rufescent above, rufescent white below; hands 
and feet fleshy white ; tail equal to length of head and body; “ fur more 
gerbille-like in character than in JZ. musculus” (or urbanus), stated to be

to Darjeeling. Stated by Hodgson to have eight teats only in the female, 
other mice having ten. Possibly his description was founded on young 
specimens. I myself was of opinion for some time that I had got two 
species of hill mice, a larger and a smaller, the latter being so much 
darker in colour, but I kept them till the young ones attained full size 
in six months, at which time they were not distinguishable from the old 
ones. Hodgson may have overlooked the pectoral mammez when he 
noted the number. 
S1zE.—Head and body, 34 inches; tail, 34 inches. 
No. 357. Mus DARJEELINGENSIS.
