its habits, being quite nocturnal, and not associating in small troops, 
but being always met with either alone or in pairs. It is very 
slow in its movements, and rarely descends to the ground, but 
when it does it walks upright like the other Indrisinw. It is found 
throughout the forests which clothe the mountains on the east coast 
of Madagascar, and also in a limited district on the north-west 
coast, the specimens from the latter locality being of smaller size 
and rather different in colour. 
Subfamily Lemurinse.—The dentition in the adult consists of 
thirty-six teeth, which, as usually enumerated, are i 2, ¢ 4, p 4, m 3. 
In the fore part of the lower jaw are on each side three elongated, 
compressed, procumbent teeth, of which the outer, usually con- 
sidered the homologue of the canine, is larger than the others. All 
the forms have long tails. Hind limbs not of the same dispropor- 
tionate size as in the last group; and the cecum much less devel- 
oped. ‘Tarsus but slightly elongated, the caleaneum being always 
less than one-fourth the length of the tibia. Toes of the hind feet 
free to the base. Habitat, Madagascar, and some of the adjacent 
Comoro Islands. 
This group contains the typical Lemurs, or rather those to 
which the term is now chiefly restricted. Two somewhat aberrant 
members make it necessary to divide it into three genera. 
Lemur..—Upper incisors separated by an interval in the middle, 
and not in contact with each other or the canine, in front of which 
they are both placed. Muzzle elongated. Ears conspicuous and 
tufted. Mamme two, pectoral. Vertebre: C 7, D 12, L 7 (or D 
13, L 6), 8 3, C 27. 
Animals much about the size of a common Cat, with Fox-like 
faces, soft thick fur, and long tails well clothed with hair. Not 
having the same 
disproportionate 
size of the limbs 
as the last group, 
they are much 
more quadru- 
pedal in their 
actions, walking 
on the ground 
or running along
