The mantle of higher vertebrates is differentiated from those of teleosts and ganoids through a very essential feature. It is no longer simple epi-. Fig. 106.—Selachian brains, showing the various development of the brain- mantle in different species. A, Brain of Galeus canis; B, of Raja miraletus. C, The cerebrum of Carcharias. All are shown in natural size. In A the Tela chorioidea is removed, giving a glimpse of the ventricle of the Thalamencephalon. thelium, but consists of numerous cells which receive and send out nerve- fibers; that is, the mantle has become a nervous mechanism. This mechan- ism, which is not much developed in the amphibians, reaches, in the reptiles, the condition of a well marked brain-cortex, differentiated from the other layers of the mantle..
