Family INDRISID^. 



Malagasy Primates recent or subfossil showing evidence of common descent from 

 ape-like ancestors, their affinity being, however, disguised by the varying degrees to 

 which the different subfamilies have become specialised in adaptation to various modes 

 of life. The dentition in every case shows reduction from the "primitive" or 

 " generalised " Primate formula (retained by the Cebidse and many of the Lemuridse), 

 such reduction being carried furthest in Chiromys, and least apparent in the Archseo- 

 lemurinse. Outer pair of upper incisors when present smaller than inner. Lower first 

 premolar generally caniniform. 



Auditory bullse generally present. Lacrymal fossa variable in position — within the 

 orbit, on the orbital margin, or on the face.
