ments delicate, a little inclined, with the spaces between them 
smaller than the exothecal cells. Diameter of corallites in 
transverse section 3/20 inch; height 2 to 2 l/2 inches.

The identity of this form with the So&enastraea Verhelsti , 
Edwards & Haime, of the Eocene of Ghent, is very remarkable; for 
fragility and increased delicacy of septa can not be admitted as 
evidence of anything more than a variation, induced probably by 
the comparative nutrition of the polypes. The dentate free edge 
of the smaller septa is very well marked, and is not noticed in 
Mi lne -Edwards ' s description. The San-Domingan Coral is there- 
fore a very interesting form, and must be considered a variety 
of the Eocene species. It differs from the recent Antillian 
species Solenastraea Bournoni , Edwards & Haime, and all the other 
known recent forms, whilst the long, corallites and crowded septa 
of the Miocene Solenastraea Turonenaia are too prominent peculi- 
arities to be mistaken.”
