Original description: 
”?he corallum is gibbous and massive; the corallites vary 
somewhat in size, but are polygonal, and are separated by con- 
solidated walls, upon which the septo-costal ends are seen. The 
septa are distinct and distant; there are ten large and ten 
small* The ten largest septa either reach the columella, or are 
attached to large pa'll; ordinarily five or six of the large septa 
have pali* The pall are long and are broader than the septa; 
sometimes two of the smaller septa unite to a larger septum. 
Columella distinct and large. Young corallites have evidently 
six systems; but the third cycle is incomplete in all the larger 
corallites
