Associated with the cortical gray matter are nerve fibres (compara- tively few in the lower, extremely numerous in the higher mammals) which form a corona radiata and connect the cortex with the more posterior regions of the brain. In the non-placental mammals the anterior commissure is very large, forming the chief association tract between the two hemispheres, but in the higher groups the corpus callosum becomes greatly developed and largely replaces it. The diencephalon is greatly reduced, the hypophysis and infundibulum being small, the latter showing traces of the saccus vasculosus and inferior lobes so prominent in the lower vertebrates. The parietal organ is lacking, but the pinealis is relatively large. It is separated from the roof of the skull by the occipital lobes of the cerebrum. It is connected with the roof of the brain by two bands or peduncles and its cavity contains a quantity of so-called 'brain sand.' A transverse groove divides the optic lobes so that they consist of four lobes (corpora quadrigemina)..
