The mode of branching and the thickness of the branches 

 differ from the description given of this species ; but the 

 Btruclure of the calices and septa fairly correspond. 



Macclesfield Bank, depth 26 to 32 fathoms. 



Psammocora J sp. 



The mode of branching and the tliickness of the branches 

 correspond with the previous species, but the columella is 

 papillary, and it might tlierefore come within the definition of 

 Stephauaria, Yerrill ; but this character hardly seems to 

 possess a generic importance. This species seems to have 

 been confused with P. plon/j)07-ay and the differences between 

 them are microscopic in character.
