molar has one inner and two outer cusps. (/orsyth Major.) 
Heel-bone elongated. 
General colour varying considerably; top of head, neck, and

Distribution—Milius’ Mouse-Lemur, though a rare species, 
is widely distributed in Madagascar, being found in the Ankay 
Forest on the north-east coast as well as along the west coast 
as far south as Mouroundava. 
Habits.—This beautiful little Lemur, no bigger than a Guinea- 
pig, is, like most of the other species of its group, nocturnal 
and arboreal, feeding on fruits and probably honey. It runs 
on all fours, but sits up to eat, holding its food in its hands. 
In the winter months it is believed to hibernate in hollow 
trees. Having scooped out a cavity big enough to contain its 
body, the little animal collects, according to the Rev. G. A. 
Shaw, sufficient loose leaves and grass to cover it; it then 
retires, and, burying itself in the heap, is sustained during its 
period of hibernation by the store of fat which, during the 
summer months, becomes deposited at’ the root of the tail, 
and swells the latter out to an enormous size.
