The anatomy of the nervous system, from the standpoint of development and function . becomes buried at the bottom of the lateral continuity of the pyriform area is not interrupted in the adult, though part THE RHINEN(). 172. 200).

In Fig. 200 wehave followed the outlines of the hippocampa] region as given by Brodmann(1909).

If we turn again to the floor of the inferior horn of the lateral ven-tricle we shall see a long curved elevation projecting into the cavity (Figs. 181,201). This is the hippocampus and is formed by highly specialized cortexwhich has been rolled into the ventricle along the line of the hippocampal fissure(Figs. 204, 209). It is covered on its ventricular surface by a thin coating ofwhite matter, called the alveus, which is continuous along its medial edge witha band of fibers known as the fimbria of the hippocampus. This, in turn, iscontinuous with the fornix (Fig. 201). In Figs. 201 and 204 there may be seen,along the border of the fimbria, a narrow serrated
