arations, the left half from a Weigert series.On the right side the cells of the hippocampal formation and adjacent structuresare drawn under the Edinger apparatus. The magnification (10 diam.) is toolow to allow the form or size of the individual cells to be represented in mostcases. The grouping is accurate. On the left side are drawn the fiber tracts ofthe medial wall. Fig. 25 Opossum, transverse section through the olfactory peduncle. De-scription in the text. Fig. 26 Opossum, transverse section just caudal to the olfactory peduncle.For the destination of the medial olfactory tract, see figure 35. Note the massof large cells in the primordium hippocampi. Fig. 27 Opossum, transverse section through the rostral end of the caudatenucleus and olfactory tubercle. The olfacto-cortical fibers arising from thetuberculum curve around the rostral surface of the nucleus parolfactorius later-alis, and appear to be interrupted in this section. Note the great extent of theprimordium hippocampi.

442 SEPTUM, HIPPOCAMPUS, PALLIAL COMMISSURES 443 Fig. 28 Opossum, transverse section a short distance rostral to the anteriorcommissure. Note that the nucleus parolfactorius medialis is imbedded in theprecommissural bundle. Note the continuity of the fascia dentata and the hip-pocampus and the close connection of the primordium with both. The rostrallimb of the anterior pallial commissure contributes most of the fibers to thealveus at this level. Fig. 29 Opossum, transverse section through the neuroporic recess. Here isseen the typical fully developed hippocampal formation with the primordiumtransversed by the anterior pallial commissure. All above the neuroporic recessbelongs to the pallium. The commissure was thicker in the Weigert specimenthan in the other. For the stria medialis Lancisii compare figure 37. Fig. 30. Opossum, transverse section through the interventricular foramenand at the caudal border of the anterior pallial commissure. The fusion of thehippocampus with the overl
