On account of the diencephalic flexure, the section must be taken obliquely to the long axis of the brain in the plane A—B of Fig. 3, in order to pass transverse to the thalamic axis. The numbers 1, 2, 8, and 4 and the letters A, B, and C, mark corresponding structures in Figs. 1 and 2, the two figures being designed to illustrate the way in which the cerebral hemispheres have been formed by the lateral evagination of the walls of the neural tube; see the text. A sulcus diencephalicus dorsalis. B sulcus diencephalicus medius. C sulcus di- encephalicus ventralis. D roof plate. V floor plate. Urodela or Anura. Epithalamus and hypothalamus are separated from the thalamus by clearly defined ependymal sulci and the thalamus is divided into dorsal and ventral parts by a third sulcus which is con- tinued backward into the sulcus limitans of the midbrain. Fig. 3 shows the relations of the diencephalic sulci as recon- structed from sagittal sections of the brain of adult Amblystoma tigrinum. The sulcus limitans is clearly preserved for its entire lengthy.
