Uppermost in the anthostele most of the .sclerites are fice (fig. 11 a-d), several of them, how- ever, together (fig. II r), and the main is in this manner develojsed into a very .solid, calcareous tube, the walls of which are formed by a close calcareous meshvvork (fig. 12) built of fused simple rods and quadruplets arranged in a layer about two to tlin'e sclerites thick. The outer walls of the .stolons are limit in the siiiiie manner. They are, however, usually somewhat stouter than the figure<l .section of an anthostele, formed by somewhat thicker sclerites. The inner part of the stolons fs for the most part filleil with free sclerites, which are considerably smaller than which build the outer wall, and among which with a. diameter of. Fij;. 11.
