Theformer goes over laterally without line of demarcation into the anterior portionof the quadrangular lobule, and the latter into the posterior portion of the samelobule in the hemisphere. 4. Folium vermis at the posterior extremity of the superior vermis. The rostral or dorsal surface of the hemisphere is subdivided by curvedtransverse fissures, which are continued across the vermis, into the followingparts: 1. The anterior part of the quadrangular lobule, continuous with the oilmenmonticuli of the vermis. 2. The posterior part of the quadrangular lobule, continuous with the declivemonticuli.

The inferior vermis (Fig. 139) is divided by transverse sulci into the follow-ing lobules: 1. The tuber vermis, next to the folium. 2. The pyramis. 3. The inula. 4. The nodidus. The caudal surface of the hemisphere presents the following subdivisions:1. The inferior semilunar lobule, occupying a large part of this surface alongits dorsolateral border. THE CEREBELLUM 199 2.
