Opossum, transverse section through the interventricular foramenand at the caudal border of the anterior pallial commissure. The fusion of thehippocampus with the overlying dorsal wall seen in the right half of the figureoccurs frequently. In these fused places fibers seem to pass from the coronaradiata into the alveus. These would probably be regarded as corpus callosumfibers. Of the three bundles constituting the stria terminalis the middle oneenters the anterior commissure, the lower one passes beneath the anterior com-missure, and the upper one passes over the anterior commissure and down infront of it. 444 J.
