Two zoaria attached to an Ostrea. Cenomanian. Le Mans. 
L. Saemann Coll. 
Seven zoaria ; one variety has long ridges and the other has the 
apertures grouped at the ends in multiserial groups, somewhat 
triangular in shape. Cenomanian. Le Mans. Tesson Coll. 
Two zoaria. Cenomanian — Gres Vert. Near Bellesme, Department 
of Orne. 
A zoarium with a stem labelled Eschara dichotoma, but which is 
indeterminable. Cenomanian. Le Mans. Old Coll. 
Three zoaria (in tube). Cenomanian. Department of the Sarthe. 
Old Coll. 
A collection of eight zoaria ; they show similar variations in the radial 
ridges to those that occur in Actinopora ; one specimen, 8 mm. in 
diameter, has the ridges raised to the height of 3 mm. at the outer 
edge, and they resemble the tooth-shaped groups of Actinopora 
diadema (Goldf.). Cenomanian. Department of the Sarthe.
