Show 604 MR. F. E. BEDDARD ON THE [Dec. 6, the rhinal furrow (on the right side); its course is longitudinal, but at an angle of about 30° with the longitudinal axis. O n the under surface the rhinal fissure is complete and very deep and wide ; on the hinder aspect of the brain it is seen to reach to within about 12 m m . of the inner corner of the hemisphere; Fig. 4. Brain of Ccelogenys paca. A, from above ; B, from the side : S, Sylvian fissure ; a, b, c, longitudinal fissures. anteriorly the under surface of the pallium is marked by a short but deepish fissure which appears to become continuous with the rhinal fissure, but is really, in all probability, a distinct longitudinal groove upon the lower surface of the pallium. The hippocampal lobe is marked by an indentation just on a level with the Sylvian fissure ; there are also faint transverse lines in front of this. The Sylvian fissure is represented by a mere notch, more emphasized on the right half of the brain than on the left. The olfactory bulbs are large. |
