The first of the secondary fissures to appear is the sulcus cinguli, which is formed about the middle of the fifth month on the mesial surface of the hemispheres, lying parallel to the anterior portion of the hippocampal fissure and dividing the mesial surface into the gyri marginalis and fornicatus. A little later, at the beginning of the sixth month, several other fissures make their appearance upon ptc.

The position of most of these fissures may be seen from Fig. 243, and for a more.
