Caiice, hexagonal, shallow, walls narrow, mostly acute 
on the edge, not prominent* Diameter usually 3 #5 aim* 
Septa distinctly lamellate, hut perforate; thick, especial- 
ly near the wall* The usual number is 24. The grouping is in 
triplets, with a free septum between each triplet - as the sur- 
faces of the calices have been damaged, as much detail as was 
desired concerning the calices could not be ascertained. The 
highest cycle of septa may extend for a considerable distance into 
the calicular cavity - half the length of the larger septa or 
even more. Septal margin dentate. Interseptal loculi narrow, 
coarse synapticula abundant* It is very doubtful if any pali 
were ever present, however, granulations or dentations not differ- 
entiated from those of the septal margins correspond in position 
to pali. 
Columella tangle moderately developed.
