Hab. N. India, Nepal, Assam, and southward to Burma, 
With regard to the difference of summer and winter pelage 
in this race [ am unable to say much personally, as the skins 
to which I have had access are sadly deficient in the necessary 
data. Mr. Adams (P. Z. 8. 1858, p. 516) points out that 
it has a seasonal change, being much darker in summer ; 
this fact had been already indicated in the Zool. Journ. vol. v. 
by Capt. Shore, and a plate given, representing a specimen 
then living in the Zoological Society’s Gardens. Mr. Blyth 
(P. Z. 8. 1864, p. 482), in some notes relating to this species, 
also remarks on its change of pelage, stating that in summer 
its appearance is very similar to J/. Gwatkinst’, and he then 
goes on to point out that Galidictis chrysogaster is an indi- 
vidual of M. flavigula in summer dress. Mr. Hodgson, in 
his unpublished drawings, now in the Zoological Society’s 
Library, gives two figures of MW. flavigula, illustrating the 
different pelages, and the summer phase undoubtedly repre- 
sents an animal of the same species as that figured under 
the name G. chrysogaster. 
Mustela flavigula borealis, Radde. 
Mustela flavigula, var. borealis, Radde, Reis. Ost-Sib, i. Deal; Pate 7, 
fig. (1-5) (1862). 
This form, described by Radde from Amurland, is rather 
larger than the typical flavigula ; the colour of the head, sides 
of face, nape, feet, tail, and hind-quarters is dark brown, as in 
the preceding form, but the light colour of the back is much 
lighter, being yellowish (gallstone-yellow, Ridgw.) instead of 
brownish. ‘Lhe yellow on the throat is also very pale. 
Dimensions (of type, from Radde) :—Head and body 
610 millim.; tail (with hairs) 460 millim.,
