A well developednucleus parolfactorius medialis appears in figure 61, quite comparable to thatin the bat and mole but placed somewhat more caudally. Fig. 62 Section at the level of the neuroporic recess showing how the primor-dium hippocampi becomes the bed of the hippocampal commissure. On the leftside where the cells are drawn, all the white space is filled by commissural fibers. Fig. 63 Rat, parasagittal

The hippocampalflexure and the upper end of the facia dentiata are cut. The section cuts length-wise of the fornix superior where that pushes between the hippocampal com-missure and the corpus callosum toward the splenium. From the septum ()to the right many cells extend back among the fornix fibers and blend with thepolymorphic layer of the hippocampus. SEPTUM, HIPPOCAMPUS, PALLIAL COMMISSURES 461. fs. c c.
