Fig. 82 Diagram of the brain of a reptile to illustrate the relations of hippo-campus and paraterminal body as defined by Elliot Smith. The outline is takenfrom the turtles brain. Herrick recognizes that the narrow ridge over the fora-men in the turtle is primordium hippocampi but describes a much larger supra-foraminal portion of the paraterminal body in lizards. Fig. 83 Diagram of the brain of the rat similar to the last. The wholecommissural system is supposed to be imbedded in the paraterminal body. 474 J. B. JOHNSTON.
