Habitat— C. Crag, S. Wood. 



The small and imperfect fragments apparently belonging to this species among the Crag 

 fossils are hardly sufficient to allow of its certain identification, though enough to justify 

 its being placed at any rate provisionally with the common recent species, which, or some 

 very closely allied forms, such as Crisia elongata of Milne Edwards, and C. patagonica, 

 D'Orbig., are found in all parts of the globe.

Polyzoario continuo, inarticulato ; ramoso vel simplici. Aut erecto et per basim 

 calcaream affixo, aut adnato vel incrustante.
