PI. , figs. 
Corallum subovate in form, 43 mm. long, 32 mm. wide, and 
about 24 mm. thick. Upper surface rounded with some slight ir- 
regularities. Beneath there appears to be a rather large attach- 
ment area. 
Calices moderately excavated, distributed over all the 
surface above the attached area. Their outline polygonal, not 
very regular in shape or size. Usual diameter 3.5 mm., a large 
calice is 4 mm., a small one only 2 mm. Walls appear when not 
damaged to be acute on the summits, but in some instances they 
might originally have been rounded. They are quite thick, as 
much as 1 mm., and are unusually compact. 
Septa in three cycles, thicker at the walls, becoming 
thinner toward the center of the calice. They also are thinner
