THE BASAL SURFACE OF THE HEMISPHERE AND THE OCCIPITAL CONCAVITY On the basal surface of the hemisphere, the two orbital concavities are well defined, as are also the interorbital keels. The olfactory bulb and tract show a considerable decline in prominence and are detachable as far back as the trigonum olfaetorium. The lateral root of the olfactory tract is much less prominent than in either the marmoset or the lemur, indicating in a general way the tendency toward deflorescence in the development of the olfactory central mechanism. The occipital concavity is pronounced in mycetcs due both to the expan- sion of the lateral lobes of the cerebellum and the further expansion of the.
