go CARNIVORES. 
The pelage consists of a full soft under-fur, mingled with long stiff hairs. In 
colour the Indian sand-badger is dirty grey both above and below, with a more or 
less marked blackish tinge on the back, most of the individual hairs being dirty 
white throughout their length, but the longer ones on the back and sides having 
black tips. The head is white, with some variable black bands, while the lower 
parts and limbs are dusky, the limbs being sometimes black. Here, then, we have 
another instance of the tendency in the present family for the under-parts to be 
lighter than the upper regions. In length the Indian sand-badger measures about 
30 inches from the snout to the root of the tail; the length of the latter, inclusive 
of the hair at the tip, being about 11 inches. 
The most marked peculiarities of these animals are, however, to be found in 
the structure of their skulls. Thus the skull differs from that of any other 
mammals, except some of the edentates and dolphins, in having the bony palate 
prolonged as far back as the level of the cavity for the reception of the condyle of 
the lower jaw. The teeth are numerically the same as in the true badgers, but the 
upper molar tooth, instead of forming a regular oblong, has its hindmost outer 
angle excavated, so that the inner border of the tooth is much longer than the 
outer one. The first premolar tooth in the upper jaw is very minute, and is often 
soon shed. 
Writing of the habits of the Indian sand-badger, from notes 
supplied by Colonel Tickell, Mr. Blanford states that it “ frequents 
undulating stony ground or small hills among jungle, and lives in fissures of the 
rocks or holes dug by itself. It is thoroughly nocturnal. In captivity it is dull 
and uninteresting, feeding voraciously on meats, fish, reptiles, or fruits, and it is 
particularly fond of earth-worms. One individual used to pass the day sleeping in 
a hole that it had dug, and was very savage if disturbed. When angry it made a 
loud grunting noise and bit fiercely. It was dull of sight, and its only acute sense 
appeared to be that of smell. It was in the habit of raising its snout in the air in 
order to scent any one who approached, much as a pig does. This animal had no 
disagreeable smell.” 
Habits. 
THE OTTERS. 
Genus Lutra. 
The otters, which, with the sole exception of the sea-otter, are included in a 
single genus, constitute the third and last main group into which the members of 
the Weasel fainily are divided. They are characterised generally by their short 
and rounded feet, 

although the hind-feet of the sea-otter are an exception in this 
respect,—their webbed toes, and their small, curved, and blunt claws. They all 
have very broad and flattened heads, furnished with small external ears, and joined 
to the long flattened body by a thick neck, which passes imperceptibly from the 
head in front into the trunk behind. The tail is moderately long, while the limbs 
are extremely short. The fur is soft, thick, and of a uniformly brownish colour over 
the whole body, except on the under-parts, where it is generally of a more greyish 
hue. The teeth of the otters are characterised by the nearly square form of the 
molar in the upper jaw, which, as shown in the accompanying figure, has its inner
