The half-dozen specimens subsumed here present no important 
differences from the Pennsylvanian forms frequently referred 
to this species. Only one corallum displays the mature devel- 
opment; the others are comparatively small and have attained 
little growth beyond the conical stage. 
Horizon and locality. Brentwood limestone : near Brentwood, 
Arkansas (Stations 145 and 147) ; Sawney Hollow, Oklahoma 
(Station 210). Morrow formation: near Ft. Gibson, Oklahoma 
(Station 301).

Description. Corallum large, 35 to 85 mm. in its major diam- 
eter, irregular in form, sub-cylindrical, sub-ovoid or ramose, 
corallites opening in all directions ; corallites polygonal in cross- 
section, bounded by walls which are quite thin in the axial por- 
tion and become greatly thickened adjacent to the surface of 
the corallum, variable in size, but commonly with a diameter 
between 2.0 and 3.5 mm.; calyces with) depth greater than 
diameter, sub-circular in cross-section, somewhat funnel-shaped, 
and bounded by thick walls; septa not apparent in the ma- 
terial at hand ; tabulae thin, numerous in the axial region where 
5 or 6 occur in the space of a diameter, convex upward, and in 
many instances arching diagonally from the corallite wall to
