Only the uncrossed portion of the tractus pallii is shown in both diagrams. At X is the vertical bundle to which Kappers has given the name tractus medianus in Chimaera and Galeus. The diagrams show that the name is applied to two entirely different tracts in the two forms, commissura pallii anterior, recessus neuroporicus. The arrow in A shows the direction of the rotation

Only the uncrossed portion of the tractus pallii is shown in both diagrams. At X is the vertical bundle to which Kappers has given the name tractus medianus in Chimaera and Galeus. The diagrams show that the name is applied to two entirely different tracts in the two forms, commissura pallii anterior, recessus neuroporicus. The arrow in A shows the direction of the rotation necessary to produce the forebrain of Chimaera from a typical selachian brain. Th^ bundle in question is a true commissure lying in the lamina supra- neuroporica and connects areas into which enter tracts from the ge- neral sensory and optic centers in the thalamus. These areas do not receive secondary olfactory fibers. These areas send down tracts which are separate from all the olfacto - hypothalamic tracts and end in the.
