It now consists of a more or less ovoid medianlobe (deeply scored by transverse furrows), and of twomuch smaller lateral portions, which project slightly be-hind the optic lobes (fig. 62, c). These Optic Lobes are pushed aside and depressed sothat they are partly covered by the large cerebral hemi-spheres (figs. 63, 64). In form they are rounded bodies,showing no trace of a transverse division. Each containsa cavity, opening below and internally into a subjacentpassage or canal, which serves to connect
