Hackel's View on the Relationship of the Sponges to the Corals. Bj H. J. Carter, F.R.S. &c. [Plates I. & II.] In the following paper I propose to describe and illustrate two new calcareous Sponges from this locality (Budleigh-Salterton, Devon), one of which will form the type of a new genus, and the other, although before noticed, has not been properly re-cognized ; also to confirm Prof. James-Clark's discovery of the true form of the sponge-cell in Leucosolenia hotryoides^ Bk., by recent observations and experiments on the structure of Orantia compressa ; further, to describe and illustrate the polype-like pore-area of Cliona corallinoides, Hancock, for the purpose of contrasting it with the views of Prof. E. Hackel on the organization of Sponges and their relationship to the Corals ; to which are added a few remarks on the groundwork or basis of his proposed classification of the Calcispongiae.
