Affinities. 
This species was founded by von Hagenow on a very imperfect 
and worn specimen. His figures give no idea of the definite lateral 
notches which adorn well-preserved specimens of this species. 
I think, however, that there can be little doubt that the specimens 
shown by Figs. 50 and 51 should be included in Heteropora 
undulata^ Hag., for a series of specimens in the Breda Collection 
establish the connection between them.
