Zooecia cylindi'ical, tapeiing below. The aperture is terminal, 
and equal in size to the diameter of the zooecia ; the apertures 
are scattered in'egularly. 
Gonoecia usually present.

The group of Bryozoa represented in the Jurassic rocks by 
Entalophora cellar ioides^ Lamx., and in existing seas by Entalopliora 
prohoscidea (Edw.), was represented in the Cretaceous period by 
several allied ‘species,’ of which E. virgiila (Hag.) is the most

typical. Pergens has identified one of the Cretaceous with the 
living species, and therefore accepted for it the name of prohoscidea. 
But the Jurassic E. cellar ioides appears to me as intimately 
related to the Cretaceous E. virgula as that form is to the living 
E. prohoscidea. If, therefore, the two latter are to be united, 
the E. cellarioides ought to be included with it, and the name 
E. prohoscidea dropped as a synonym. 
The relations of the Entalophoridae to the Diastoporidae are 
illustrated by Fig. 24, which represents the discoid, encrusting 
base of an Entalophorid. Had the central part been broken away 
the specimen would have been indistinguishable from a Berenicea. 
But the erect, solid axis, which is shown, broken across trans- 
versely, near the centre of the figure, proves that the specimen
