4 MR. O. THOMAS ON THE [Jan. 3, 
uniform, Dr. Anderson, in the work quoted above, has fully de- 
scribed and figured the skulls and dentition of the Indian forms ; and 
the African ones are very similar, if we except H. (Ichneumia) albi- 
cauda, which has, of course, as forming a distinct subgenus, many 
characters peculiar to itself.

Size large, about 20 inches; form slender; tail about 4 to 5 inches 
shorter than the head and body. Fur long, especially on the ramp 
and basal quarter of the tail, where the longer hairs are often 4 or 
more inches in length. General colour dark grizzled grey-brown, 
the hairs annulated with dark red-brown and creamy yellow, the tips 
of the back hairs darker yellow. Underfur thick and woolly, bright 
rufous in colour. Tip of tail shining black, the hairs elongated so 
as to form a distinct tassel, sometimes reaching 5 inches beyond the 
vertebre. Feet dark brown. Underside of hind feet generally quite 
naked, the part under the caleaneum sometimes, though rarely, hairy.
