THE TRUE LEMURS. ‘SUB-FAMILY “Ht 
LEMURIN. 
The third sub-family of the Zemuride contains the True 
Lemurs, which are characterised by the possession of a soft, 
thick, and woolly fur, the head rounded behind, with a 
specially elongated muzzle. They have small and oval ears, 
with the exterior aspect covered with long hair, but the inside 
naked, except round the margin. Their hind-limbs do not 
show so great a disproportionate length compared to that of 
the fore-limbs, as in the next sub-family, the Zudrisine. ‘The 
ankle-bones (avsws) are only slightly elongated, and their toes 
are not united bya membrane. Their long and bushy tail is 
sometimes longer and sometimes shorter than the body. The 
females produce one or two, nearly naked, young at a birth, the 
mamme being either two or four in number. ‘The skull pre- 
sents a central ridge on the frontal bone, and its facial portion 
is much elongated, the inter-orbital space being depressed and 
wider, and the orbits also directed somewhat outward and less 
straightforwardly than in several of the genera already noticed. 
The maxillary bones are generally much reduced, and the in- 
cisor teeth carried by them not unfrequently entirely aborted. 
The teeth in this Sub-family vary in number from 32 to 36, 
the dental formula being 192, C+, P3,M32. The foot is 
slightly elongated by the lengthening of the zaview/are bone of 
the ankle, the others being short. In the wrist (carpus) the 
central bone (ceztvale) may be present or absent ; its absence, 
however, is a character which is met with otherwise only in 
Man, the Chimpanzees, and the Endrina and some other 
Lemurs, to be described later on. The caecum is not markedly 
developed.
