St. pumpellyi 
* 9m 
The type specimen of this species is a worn specimen and 
did not show the pillars characteristic of Stylocoenia . However, 
in the fall of 1900 while collecting along the Flint Kiver, near 
Bainhridge, Georgia, I procured some very good material, which 
shows conclusively that the species is a Stylocoenia and not an 
Astrocoenia . By using these specimens I am able to furnish the 
follo?/ing revised description: 
CoralXum encrusting, forming masses as much as 75 mm. thick, 
with the upper surface thrown into gibbosities. 
The corallites may be crowded, as was originally described 
for the type specimen or they may be separated by walls sometimes 
as much as 1 mm. across. When the wall is rather thick its 
upper surface is densely granulated and often there are short 
costae around the edges of the calices. Distinct, rather pointed 
pillars, ’which possess granulated longitudinal striations, are 
common over the surface of the corallum. These usually, if not 
always, are connected with a large septum of a calice. Diameter 
of the calices, from 1 to 1.5 mm,
