8 CARYOPIIYLLIA. 



rather loose laminse. Septa in six complete systems and four cycles, 

 thin, prominent, sharp, and rounded on the edge, sparsely granulated. 

 Twelve pali, equal, large, flexuous, with few and comparatively large 

 granules. 



The young are elongated, and show much diversity in their devel- 

 opment as regards the columella and pali; when the columella is 

 developed early, the pali are much delayed in their appearance, and 

 vice versa. 



The differences between this species and 0. cyathus are not very 

 striking; our specimens are, however, always smaller, slenderer, and 

 have the columella much less developed. 



None of my specimens attain the size of a full-grown Mediterranean 

 specimen.

Off Tortugas in 60 to 68 fathoms. 



Caryophyllia Berteriana ? Duchass. 

 Caryophyllia Berteriana DoCHASSAlNG. Anim. rail, des Antilles, 1850. 



A single specimen obtained in 08 fathoms off Tortugas. with the 

 preceding species, differs from it and from C. formosa by its very prom- 

 inent primary and secondary septa, thus resembling the figure of 

 Milne-Edwards and Haime. The systems of septa are, however, 

 all complete and very regular, so that there are twelve pali, as in 

 all other Caryophyllia". The descriptions of Duchassaing and Milne- 

 Edwards and Haime appear to have been made from the same 

 specimen, perhaps an exceptional one.

I have selected, from the numerous authors who have mentioned 

 this coral, those who have given figures representing the type ap- 

 proaching nearest my specimen. Not having the materials at hand 

 to enable me to pronounce an opinion on Dr. Duncan's sweeping 

 reduction of all the European species to a single one, and not wishing
