I. — A Dejtrn'pfi'on of two neio Calcispongife, to which is 

 added Confirmation of Prof. James-Clark's Discovery of the 

 True Form of the Sponge-cell {Animal), and an Account of 

 the Poh/pe-like Pore-area o/*Cliona corallinoides contrasted 

 with Prof. E. Hiickel's View on the Relationship of the 

 Sponges to the Corals. By H. J. Cauter, F.ll.S. &c. 



[Plates I. & n.] 



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 s{)onge-cell in Leucosolenia hotryoides^ 

 Bk., by recent observations and experiments on the structm-e 

 of Grantia 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.
