Figures 22-24 show cross- sections through the anterior, middle, and posterior parts of the hemisphere, respectively (cf. Fig. 10, p. 76). Internally of the putamen is the globus pallidus (Figs. 20, 23) and internally of both of these is the olfacto-striatum (Figs. 21, 22, 23). These comprise the old striatum, directly derived from the striatum of Ichthyopsida. Above these is the "dorsal ventricular ridge," a new structure which is not represented at all in fishes and amphibians. The whole of this was called "hypopallium" by Elliot Smith because its relations are more.
