ENTALOPHOEA. 
Pergens ^ and Canu.^ But the former author assigns to E. pulcheUa 
izooecia having a diameter of *18 mm. to -20 mm., and an aperture 
of *06 mm. The best figures of the Cainozoic E. imlchella are those 
by Manzoni®; his figure Zbc shows a specimen of the natural size 
and magnified about 17 dia. ; calculated from this figure the zooecia 
bave a diameter of from *35 to *47 mm., and the aperture is *15 to 
*175 mm.
