Hab. North-eastern Siam ; type from Nan, alt. 200 m. 
Type. Adult male. B.M. no. 1.11. 8.5. Original num-

Another ferret-badger from Tonkin has still smaller 
teeth :-— 
Melogale tonquinia, sp. n. 
Size doubtful, but the single immature skull is already 
rather longer than in adult female WV. p. /aotum. General 
colour brown rather than grey. White head-markings at a 
maximum, the white nape-band expanded on the crown to 
within half an inch of the pre-aural light stripe, which is 
connected behind the eyes with the frontal patch. Dark 
eye-rings narrow. LHars completely whitish, inside and out. 
Light colour of cheeks, throat, chest, and inguinal region 
strongly suffused with yellow—though this is probably an 
individual peculiarity. Forearms and hind limbs brown, 
hands and tips of toes white. 
Teeth decidedly smaller than in other species, the greatest 
diameter of p* only 8-0 mm., the transverse diameter of m' 6:7, 
and the internal antero-posterior diameter of the latter only 
3°8 mm. ; similarly, below the carnassial is only 7°6 x 3°7 mm.
