 knowledge of the Calcispongia, and the Author's investigations on 

 Porosphcera would be eagerly awaited by palseontologists. 



The Author replied that it was satisfactory to know that the 

 importance of these sponges from an evolutionary point of view was 

 recognized by so competent an authority as Prof. Sollas. The 

 complete fusion of the spicules in the fibres was fairly recognizable 

 in the material examined. He thanked the Fellows for their kind 

 reception of the paper.
