The mode of branching and the thickness of the branches 
differ from the description given of this species ; but the 
structure of the calices and septa fairly correspond. 
Macclesfield Bank, depth 26 to 32 fathoms. 
Psammocora , sp. 
The mode of branching and the thickness of the branches 
correspond with the previous species, but the columella is 
papillary, and it might therefore come within the definition of 
Stephanaria , Verrill; but this character hardly seems to 
possess a generic importance. This species seems to have 
been confused with P. planipora, and the differences between 
them are microscopic in character.
