The transverse section is that of Entalophora^ but eccentrically 

 arranged, for it is impossible to distinguish the tubes of the dactyle- 

 thrae. There is no basal lamella, and gemmation occurs around 

 the zoarial axis. The latter, with the reduction of the dactylethrae 

 is eccentric with relation to the geometrical center. 



Occurrence. — Cretaceous (Campanian) : Longuesse (Seine et 

 Oise), France. 



Plesiotypes.—Canu collection and Cat. No. 68977, U.S.N.M.
