Cebidse. The thumb is not at all opposable, and all the fingers 
are armed with sharp claws. The hallux, or thumb-like great 
toe, is very small ; the tail is long and not prehensile. The two 
genera Hapale (9 sp.), and Midas (24 sp.), are of doubtful value, 
though some naturalists have still further sub-divided them. 
They are confined to the tropical forests of South America, and 
are most abundant in the districts near the equator.

The Lemur idoe, comprehending all the animals usually termed 
Lemurs and many of their allies, are divided by Professor Mivart 
— who has carefully studied the group — into four sub-families 
and eleven genera, as follows : — 
Sub- family Indrisinse, consisting of the genus Indris (5 sp.), 
is confined to Madagascar. 
Sub-family Lemurinae, contains five genera, viz. : — Lemur , 
(15 sp.) ; Hapalemur (2 sp.) ; Mierocebus (4 sp.); Chirogaleus 
(5 sp.) ; and Lepilemur (2 sp.) ; — all confined to Madagascar. 
Sub-family FTycticebinae, contains four genera, viz. : — Nydicebus 
(3 sp.) — small, short-tailed, nocturnal animals, called slow-lemurs, 
— range from East Bengal to South China, and to Borneo and 
Java; Loris (1 sp.) — a very small, tail-less, nocturnal lemur, 
which inhabits Madras, Malabar, and Ceylon ; Perodicticus (1 sp.) 
— the potto— a small lemur with almost rudimentary fore- 
finger, found at Sierra Leone (Plate V., vol. i., p. 264); Ardocebus 
(1 sp.) — the angwantibo, — another extraordinary form in which 
the forefinger is quite absent and the first toe armed with a long 
claw, — inhabits Old Calabar.
