the corpus striatum (together with the nucleus amygdalai) and 

 the floor of the fossa Sylvii, i.e., the insula Eeilii. It did not 

 include what Eeichert calls the " tractus olfactorius " (the 

 bulbus and pedunculus olfactorius), although he recognised that 

 this is attached to the " Stammlappen." 



It will be observed that the term "pallium" was thus 

 originally employed to designate that cortical area (with its 

 associated medullary layer) which is free from (i.e., is not 

 adherent to the surface of) the corpus striatum. As such the

name is of little morphological value, for while it groups 

 together the greater part of the neopallium with the whole of the 

 hippocampus and a small part of the pyriform lobe, it excludes 

 a small area of the neopallium (the insula Eeilii of Human 

 Anatomy) and the greater part of the pyriform lobe from the 

 " mantle,'' and includes them with the corpus striatum in the 

 " Stammlappen." If any part of the pyriform lobe constitutes 

 a part of the " pallium," there can be no valid reason {i.e., if 

 the proposed subdivision is to be natural and based upon sound 

 morphological grounds) for excluding the rest of the same 

 histological formation, simply because it does not happen to be
