176 GEOGRAPHICAL ZOOLOGY. [part iv. 



Cebidae. The thumb is not at all opposable, and all the fingers 

 are armed with sharp claws. The lialkix, 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.

j 1.2.3.4—2.3.4 : 



The Lemurida?, 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 : — 



Suh-family Indrisinffi, consisting of the genus Indris (5 sp.), 

 is confined to Madagascar. 



Sub-family Lemurinas, contains five genera, viz. : — Lemur, 

 (15 sp.) ; Hapalcmur (2 sp.) ; Microcehus (4 sp.) ; Chirogaleus 

 (5 sp.) ; and Lcpikmur (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); Ardoccbus 

 (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.
