Coral lum compressed conical, attached by a small, pointed 
base. The best specimen, which is taken as the type, has a 
greater diameter at the calic© of 25.8 mm., lesser diameter 18 
xam. , height 27 mm. The specimen is somewhat crushed. 
Wall rather thick, very compact. Costae distinct, around 
the caiice subequal, as the base is approached every alternate 
one becomes more indistinct, ultimately disappearing. At the 
margin of the caiice they are decidedly crowded, less so inferior- 
ly. Edges subacute. 
Septa thicker at the wall, very much crowded, numerous, 
about 96, or five complete cycles. The members of the first, 
second and third cycles appear to be continued to the axial 
space
