Fig. 9 Emys lutaria, 10 mm., three parasagittal sections. In A the nervus 

 terminalis enters the rostral end of the hemisphere on its medial surface. It 

 contains some ganglion cells. In B the olfactory bulb and ventral part of olfac- 

 tory nerve are shown. The section passes through a ganglion midway of the 

 length of the nervus terminalis. In C a peripheral ganglion is cut at the point 

 where the nervus terminalis separates from the dorsal division of the olfactory 

 nerve to enter the wall of the medial diverticulum (vomero-nasal organ).
