 Lemurs and Apes certainly derived from a common stem (pp. 417-425). 

 Lemurs barely separated subordinally. " Tarsius possesses at once the 

 iTiost generalized and the most pithecoid brain of all the Lemuroidea" (p. 

 424). "The brain of the Primates was derived from some Insectivore- 

 like type, the cerebral hemispheres of which attained a precocious devel- 

 opment " (p. 425).

Tarsius extremely primitive in brain structure, related to Apes but still a
