Type.—Adult skull, female. B. M. No. 21. 7.16.4. Collected by Mr. J. P. 
Mills. Presented by the Bombay Natural History Society, “‘ Brought in by 
Nagas ’”’—J. P. M. : 
This porcupine may be distinguished from its only near relative A. klossi by 
the more swollen character of the face, the large broad nasals, parallel-sided 
interorbital space, and subequal frontals and parietals. 
Anderson’s Hystrix yunnanensis is a species with quite small nasals, allied 
to javanicus, and Blyth’s bengalensis is certainly the same as hodgscni, as I have 
been able to prove by some measurements of the skull of its type kindly sent me 
by Mr. Stanley Kemp of the Indian Museum. 
Mr. Mills is to be congratulated on his discovery of this fine addition to the 
Assam fauna. 
(C) ANEW FERRET BADGER (HELICTIS) FROM THE NAGA HILLS. 
Among the specimens from the Naga Hills, presented by Mr. J. P. Mills to the 
Bombay Natural History Society, are four specimens of a Ferret-Badger (Helic 
tis). It proves to belong to the small-toothed group of these animals, the true 
Helictis, not hitherto known to occur within the bounds of British India, those 
previously known being members of the other group, that of the large-toothed 
forms. In my opinion however these latter should be considered as of a different 
genus, for which the name Melogale is available. 
Up to the present, the true small-toothed Helictis has been only known from 
China, so that its occurrence in the Naga Hills is of much interest. And even in 
China its range is rather to the East and South, than in the region 
approximating to the Naga Hills. 
The species is clearly new, and may be described as tollows :— 
Helictis millsi, sp. n. 
Size about as in H. moschata. Fur shorter than in that animal, in summer 
pelage only about 10 mm. long on the back, and almost without underfur, in 
winter pelage about 20 mm., with a fair development of under fur, but far less 
than in the Helictis of the lower Yang-tse. General colour “ dark purplish grey ”’ 
very different from the drabby brown, or dark wood brown, of the Chinese animal. 
Ground colour of top of head from muzzle down nape to withers, much darker, 
near blackish brown. White markings present, well defined, the white patches 
about of the same size as in examples of moschata from the lower Yang-tse, larger 
than in the typical specimens from Canton, median white line interrupted on 
nape, and ending on withers. Under surface dull whitish as usual, the sides of 
the belly grey. Ears grey with white edges. Hands and feet grey, the digits 
sometimes whitened. Tail blackish grey washed with whitish, the white not 
specially developed. 
Skull apparently very like that of H. moschata, except that the anteorbital 
foramina are lower and more transversely extended. Teeth quite as in moschata. 
Dimensions of the type, measured on skin :— 
Head and body 365 mm. ; tail 163 mm. 
Skull, greatest median length 79.6 mm. ; zygomatic breadth 46 mm.; in- 
terorbital, breadth 20 mm. ; mastoid breadth 36.2 mm. ; anteorbital foramen 
5.63.5 mm. ; palatal length 38mm. Front of canine to back of m’ 24.7; 
length of p* on outer edge 64 mm. 
Hab.—Naga Hills, Assam. Type from Mokokchung, 5,000’. 
T ype.—Adult male in summer pelage. B. M. No, 20.6.6.8. Original number 
10. Collected 10th October 1919 and presented by J. P. Mills, Esq., to the 
Bombay Natural History Society, and by them presented in turn to the National 
Museum. Four specimens examined. 
This fine species is at once distinguishable from the Chinese species by its 
general colour, dark grey instead of drabby brown.
