INDRODON MALARIS, gen. et sp. nov. 
Char. gen. Family Anaptomorphide, suborder perhaps Lemuroidea, as 
indicated by the dentition only. It differs from Anaptomarphus in three 
points. First, there are three superior incisors ; second, the first (third) 
premolar has no internal lobe; and third, there is a distinct posterior in- 
ternal tubercle on the first and second superior molars. 
The animals of the Hocene period of the family of the Adapidw, may be- 
long to the Lemuroidea, but the evidence which I have derived: from the 
feet of Pelycodus* has led me to refer them} to the Insectivorous division 
of the Bunotheria, to the neighborhood of the Tupmide and Erinaccide. 
At the same time I retained provisionally the genera with three and two 
superior premolars in the suborder Lemuroidea, although the foot struc- 
ture of these extinct genera is yet unknown. I also indadvertently defined 
the Lemuroidea as having quadrituberculate superior molars, a character 
which I well knew to be wanting in various extinct and recent genera 
where they are tritubercular. T'wo families were proposed} for the Eocene 
lemuroids, which are defined as follows :
