Fig. 9 Cistudo Carolina, adult, median sagittal section of forebrain. The 

 pallial comnaissure has descended into close relation with the anterior commissure 

 so that the neuroporic recess is nearly obliterated. The median section is accu- 

 rately reconstructed from sagittal sections. The dotted outline of the hemi- 

 sphere is diagrammatic. For the explanation of the fibers shown, see text.
