A corresponding arrangement is noted in the preparation of the cæcum of Cercopithecus campbellii ([Fig. 433]). The large intermediate fold is joined by the ventral vascular fold, thus defining the lower boundary of ventral ileo-cæcal fossa.

(C) Union of both vascular folds with the intermediate non-vascular fold.
