In a preliminary section the nature and probable origin of the deposits at 

 Ampasambazimba will be briefly discussed. These deposits are especially rich in 

 mammalian remains. In the comparatively small area already explored some 

 60 skulls of Lemuroids, mostly in an excellent state of preservation, and representing

several new species and one new genus, have been found. In addition to these 

 Primate remains at least 200 skeletons of Hippopotami of all ages have been exhnmed, 

 besides numerous remains of Cryptoprocta, Centetes, and other Insectivora. 



Along with these vestiges of an extensive subfossil mammalian fauna large numbers 

 of bones of jEpyornis, Chelonians, Crocodiles, Lizards, &c. have been found. It is my 

 intention, however, at present to confine myself to a description and discussion of the 

 fine series of Lerauroid remains which have been brought to light at Ampasambazimba. 

 These not only form a most valuable contribution to our knowledge of the strange 

 extinct fauna of Madagascar, but also throw light on the origin and affinities of the 

 existing Primates of that interesting island. 



After discussing the character and probable origin of the fossiliferous beds at 

 Ampasambazimba my aims in the present memoir will be : — 



1. To give a detailed description of the various new species or genera of Lemuroids, 

 drawing special attention to such characters as tend to explain the affinities of 

 the different forms.
