The diagonal fissure (S. diagonahs) begins in front of the stem of the lateral fissure and runs upward and forward. Its form is very variable. 4. The transverse fissure outs obhquely into the dorsal border in front of the sagittal pole. It is short and deep and commonly communicates with the suprasylvian and coronal fissures, but may be separated from the former. 5. The marginal fissure is distinct. It extends
