This commissure lies in the Lamina terminalis near the base, and is ex- ceedingly constant (Figs. 18, 76, and 100). The various bundles are best known at present in the reptiles. Everything now known indicates that the relations are the same in the other vertebrates as in reptiles. The commissures

It is not usually to be seen in the uncut brain, because it is covered in by the brain-mantle, and lies really in the floor of the enmantled ventricle. Only in fishes, where the mantle is represented by a thin membrane, is it to be recognized through the, mantle. In this case it forms what is called the frontal lobe. The more highly developed the mantle,—as in mam- mals,—the more unimportant appears the structure^so large relatively.
