In some of the smallest species of Gyren-cephala the exposed surface of the cerebral hemi-spheres may be smooth, or with few and simplefissures (fig. 98, II;/rax ; fig. 101, Tragulus ; and vol. ii. fig. 147).This state does not, however, relate to reduction of hemispheres, but may coexist with their.
