(A.) NEW AND INTERESTING MAMMALS FROM THE MISHMI HILLS, 
BY 
OLDFIELD Tuomas, F.R.S. 
(Published by permission of the Trustees of the British Museum.) 
In a fine collection of mammals from the Mishmi Hills made for the Survey 
by Mr. H. W. Wells there occur the following forms worthy of special note. A 
ull report on the collection will appear later. 
Tupaia belangert versure, subsp. n. 
Near 7’. b. assamensis, Wrought., in general colour, but the fur longer, the 
shoulder stripes more diffuse—in fact scarcely perceptible, and the buffy ends 
of the hairs of the chest and middle line of belly more strongly ochraceous. 
Hairs of inguinal region dull buffy with slaty bases, these hairs being wholly 
buffy in assamensis. 
Skull as usual in belangeri. 
Dimensions of the type, measured in the flesh :— 
Head and body 199 mm. tail 184 mm., hindfoot 43° 5 mm., ear 20 mm. 
Skull, greatest length 49 mm., zygomatic breadth 25 mm. 
Hab.—Mishmi Hills. Type from Dening, 2250’. 
Type.—Adult male B. M. No. 21. 12.5.9. Original number 1629. 
Collected 3rd April 1921, by H. W. Wells. Presented by the Bombay 
Natural History Society. 
This Tree Shrew of the far North-eastern corner of British India differs from 
that of the rest of Assam in a curiously similar manner to that in which 
Dremomys l. subflaviventris does from D. 1. garonum, for the buffy of the 
undersurface is here ochraceous as compared with yellowish exactly as in 
the corresponding races of the squirrel from the same two areas. 
The only other form that comesin question is 7. b. chinensis, and on the basis 
of our Teng-yue specimens of the latter, the Mishmi specimens are distinguishable 
by their much darker general colour, and their ochraceous-washed undersurface. 
In working out this Tree-shrew I have again examined the form found in 
Sikkim, which has been long known, but has hitherto been vaguely assigned to 
T. belangeri belangeri, whose type locality is Pegu. 
Now that better series are available, it is natural to find that the Sikkim form 
deserves a special name, and it may be called— 
Tupaia belangeri lepcha, subsp. n. 
Size rather less than in the average of belangeri. General colour olivaceous 
grey, paler than in assamensis and versure, the back without any brownish or 
rufous tone such as is found in subspecies belangeri. Shoulder stripes scarcely 
perceptible. Chest and middle line of abdomen washed with pale buffy, about 
as in assamensis, paler than in versure. 
Dimensions of the type, measured in the flesh :— 
Head and body 154 mm., tail 173 mm., hindfoot 40 mm., ear 16 mm. 
Skull, greatest length 46 mm., condylo-basal length 44 mm., zygomatic 
breadth 24 mm. 
Hab.-—Sikkim and Bhutan. Commonly recorded also as from Nepal, but this 
appears to have been based on Hodgson’s later specimens, which were from 
Darjiling and not Nepal. Type from Narbong, Darjiling, 2000’. 
Type.—Adultfemale. B.M. No. 15.9.1.44. Original number 6467. Col- 
lected 14th March 1915 by C. A. Crump. Presented by the Bombay Natural 
History Society. 
Hitherto always referred to 7. belangzri belangeri, but clearly subspecifically 
distinguishable.
