the rhinal furrow (on the right side) ; its course is longitudinal, but 

 at an angle of about 30° with the longitudinal axis. 



On the under surface the rhinal fissure is complete and very deep 

 and wide ; on the hinder aspect of the brain it is seen to reach to 

 within about 12 mm. of the inner corner of the hemisphere ;

anteriorly the under surface of the pallium is marked by a short but 

 deepish fissure which appears to become continuous with the rhinal 

 fissure, but is really, in all probability, a distinct longitudinal groove 

 upon the lower surface of the pallium. The hippocampal lobe is 

 marked by an indentation just on a level with the Sylvian fissure ; 

 there are also faint transverse lines in front of this. The Sylvian 

 fissure is represented by a mere notch, more emphasized on the right 

 half of the brain than on the left. 

 The olfactory bulbs are large.
