The author shows that Cliona or a similar burrowing spong^e infested 

 certain brachiopod shells as early as the Devonian, and that similar forms 

 were as common ujion the fossil Ostieidte as they are ujion the living*.

 Ostreidre, although they are so common an enemy to living oysters.

 idea of the characteristic Carboniferous forms of the central coal basin.
