Mossel Bay: ?MB 7 Q; ?MB 22 F; ?MB 27 J; ?MB 48 D. Description Colonies are of rounded, lobed, upright or even slightly stalked, shape. No sand is present either on the surface or within the colony. The test is of a milky or semi-transparent appearance. Large vesicular cells are present in the test and these were noted by Sluiter (1898) as a distinguishing feature of the mm. Fig. 24. Eudistoma illotum (Sluiter). Larva. In the colonies from False Bay the zooids are 3-4 mm. in length, and slender with a long waist as in the type specimens. The zooids in the colonies collected from Mossel Bay range from 2 to 6 mm. in length and have only a short waist. I am therefore a little doubtful of the identification of the material from Mossel Bay. Larva No larvae were found in the present material, but Sluiter's type specimens, which I have been able to examine, have larvae (fig. 24). These range from 0-96 to 1'20 mm. in length, from the end of the papillae to the base of the tail. There are 3 anterior papillae with a pair of narrow lateral ampullae between each two adjacent papillae, on each side. Both ocellus and otolith are present. Only one larva was found in each breeding zooid, perhaps owing to the large size of the larvae. Reliable characters in the genus Eudistoma are few, there is considerable.
