176 GEOGRAPHICAL ZOOLOGY. [part iv. 



Cebidae. 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 Hajmle (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 Lernuridae, 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 Lemurinse, contains five genera, viz. : — Lemur, 

 (15 sp.) ; Hapalcmur (2 sp.) ; Microcebus (4 sp.) ; Chirogaletis 

 (5 sp.) ; and Lepilemur (2 sp.) ; — all confined to Madagascar. 



Sub-family Nycticebinse, contains four genera, viz. : — Nycticcbus 

 (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 ; Pcrodidicus (1 sp.) 

 — the potto — a small lemur with almost rudimentary fore- 

 finger, found at Sierra Leone (Plate V., vol. i., p. 264); Arctocebus 

 (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.
