The outstanding feature regarding it is its lack of definition and the entire absence of any tendency toward convokition which characterizes this nucleus in the higher primates. In tarsius the dentate nucleus is small and, as might be interred from it, the lateral lobes of the cerebellum are poorly developed. This con- dition indicates an animal provided with a low degree of eoordinative control,.
