with some black hairs towards the outer side. The female, on 

 the contrary (no. 99.3.5.2), with the same history and presumably 

 from the same locality, is much paler, the general colour being- 

 yellowish brown, the upjjer surface of the tail being the same 

 yellow-brown colour as the hind-quarters. On the fore leg the 

 blackness scarcely extends below the knee, the blackness of the 

 outer side of this area, so noticeable in the male, being scarcely 

 in evidence. Similarly the hind legs are yellowish brown in 

 front below the hocks. I do not know whether these differences 

 are sexual, seasonal, or individual. The third specimen 

 (no. 99.3.5.3), an immature unsexed animal, resembles the 

 female. 



So far as the coloration of the legs is concerned, the examples 

 I refer to iV". raddeanus are more like specimens in the British 

 Museum from Southern China than they are like lY. caudattts. 

 These Southern Chinese specimens, which appear to me to be 

 specifically the same as JS^. griseus A. M.-Edw.*, described from 

 Eastern Tibet, were obtained by Berezowski at Loung-nyou-fou 

 in the mountain of Sze-chuen (nos. 96.11.4.7-8) and by Mr. F. 

 W. Styan at Ichang on the Yangtse-kiang (nos. 1.3.2.4 and 

 95.7.4.1-2). A young example was also brought from the same 

 locality by Mr. P. Montgomery (no. 96.11.4.7-8). 



Except that these southern forms are covered with a thick 

 coating of comparatively short hair and have the hairs of the tail 

 also shorter and scantier, they do not differ very noticeably from 

 JSf. raddeanus. The skin of the tail measures from 4 to 5 inches, 

 and, including the hair, the entire tail may reach 10 inches. The 

 hairs of the tail, however, are black both above and below, and 

 in this particular resemble those of N. caudatus rather than of 

 xY. raddeanus ; and the white throat-patch is tinged with yellow 

 at the margins. The outer and posterior sides of the lower 

 portion of the front leg are blackish, the knee, the inner side of 

 this area, and the feet being darker or paler fawn. The hind 

 legs, below the hock, are brown behind, fawn or greyish fawn in 

 front. 



Like N. raddeanus^ N. griseus exhibits instructive variation in 

 colour. Of the three above-mentioned skins from Ichang no two 

 are alike. In one male example shot on September 9 the coat is 

 poor and of a dirty yellowish brown, with a very distinct black 

 spinal stripe, and the feet are a warm ferruginous or rusty-yellow 

 tint. A second specimen, shot on the same date and also a male, 

 has no distinct spinal stripe, the coat being a mixture of brown 

 and grey. The feet are nearly white. The third specimen, also 

 a male but shot in December, is thicker-coated and much more 

 richly coloured with dark brown than the others, though more 

 approaching the second specimen ; the spinal stripe is traceable 

 but less differentiated than in the first specimen, owing to the 

 darker tint of the rest of the body ; the feet are fawn — that is to
