September 28. — (Fig. 21.) Marginal tentacles on original disc 10-12 mm. in length except over cut, where they are reduced to about I mm. Labial tentacles 2-3 mm., except over cut, where they are scarcely visible. The lateral wound is closed by thin new tissue, but near its distal end two small tentacles appear, one arising from each side of the cut. Proximal to the tentacles the cut margins have united longitudinally and distal to the tentacles a broader area of new tissue fills in the space between the old margins. The course of the septa is indicated by the dotted lines in Fig. 21. It is evident.
