These features seem to indicate that the spines are gradually absorbed by the growth of the surrounding coenosteum, and that they do not grow materially after the incorporation of the branchlet in the mesh- work of the colony. At first glance we might presume dimorphism to exist among the dactylopores, small dactylopores being found as circular holes in the coenosteum in great numbers between the spines (Figs. 3, 4). On the other hand, it is obvious that the spines do not quite correspond either to the nariform or the water- spout-like spines of Errina. In their disposition, especially on the branchlets, they are reminiscent of the nariform spines of Eu-Errina, but it is also evident that they are connected with, or probably â ,;'i.
