The ectomarginal fissure lies aliove and nearly parallel to the posterior part of the sui>;Mi fissure. s. The entomarginal fissure lies idon;; the |)oslerior part of the dorso-medial border. 9. The calloso-marginal fissure eonsisis of two separate parts. The more extensive pos- terior part is termed llie splen-al fissure. It extends from the tentorial aspect of the hemi- sphere in a direction jiandlel with the corpus callosum nearly to the middle of the medial surface; it is continued by tlie cruciate fissure and may be also connected with the (?oron:d tissure by a branch which passes obli(|iiely upward and forward. The anterior part, tlie genual fissure, lies about midway between tlie :inicrior part of the corpus callosum and the border. 10. The cruciate fissure runs obliqu ly ;ind forward from the anterior end of the splenial on the inner surf;\ce of the hemisphere, cuts obliquely into the margin about its middle, and iisindly joins the dorsal branch of the supr:i\ I he rhinenccphalon.
