Astrocoenia incrustans 
Columella styliform, rather prominent, compressed. This 
coral can not he referred to St enhance oeni a because there are no 
pali and the septal margins are dentate, instead of being entire. 
However, set exhibits all the characteristics of Astrocoenia . In 
the size of the calices, number of the septa and character of 
the septal margins , it resembles A. due r deni , but differs from 
that species by the apparent absence of mural spines. Notwith- 
standing this, it is not impossible that the type specimen could 
be a portion of a corallum of A. due r deni , the styles being 
absent from the area whence it was derived.
