 the nucleus caudatus and nucleus lenticularis of the corpus striatum, 

 the claustrum, and the amygdaloid nucleus.

The corpus striatum is a large ovoid mass, which is situated in 

 front, and on the outer side, of the optic thalamus. It is composed 

 of two collections of grey matter, one of which is intraventricular and 

 the other extraventricular. The intraventricular portion is called
