Size large, scarcely less than in C. bedfordice and andersoni. Fur (in winter) 8-9 mm. in length on the back. General colour above coarsely-lined cinnamon-brown in most specimens, but darkening in old individuals to a rich and beautiful cinnamon-rufous or hazel of unusual intensity. Sides paler, without marked line of demarcation from either back or belly ; under surface broadly washed with pinkish buff, the bases of the hairs slaty as usual. Glandular patches present on flanks, but not conspicuous. Forehead lined cinnamon-brown. Ears well-clothed with rufous hairs. Upper surface of hands and feet buffy whitish. Tail shorter than in the Japanese species above referred to. wellhaired, sharply bicolor, brown above darkening terminally to black, cream-buff below. Mannna1 2- 2 = 8. Skull, as compared with that of C. andersoni, more thickly built throughout, the brain-case higher and rounder, and the in ter orbital region broader. Palatal foramina long, rather narrow, reaching back very nearly to the level of the front of ml. Posterior nares of typical ItJvotomys-p&ttevn ; but the ridge that runs forwards in continuation of the pterygoid processes is unusually sharply developed as it approaches the overhanging palatal ledge. Bullae large and rounded. Incisors broad and heavy in old specimens. Molars of normal pattern ; the degree to which enamel-spaces are confluent is variable, as usual in this group. Last lobe of m' sometimes elongated, sometimes quite short. Dimensions of the type, measured in skin :-Head and body 116 111111. ; tail 45 ; hind foot 18-5 ; ear 13. Skull-greatest length 27-l mm. ; basilar length 24; zygomatic breadth 15 ; length of nasals 8*3 ; interorbital breadth 4 ; height from alveolus of nr to supraorbital edge 8-2 ; diastema 7*9 ; palatal foramina 5*3 x 1*5; length of upper molar series (crowns) 6-1. other specimens measui•e as follows : - Head & body.

Collected 25 November, 1905, at Min-gyong.
