8 CARYOPIIYLLIA. 



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

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

 Twelve pali, e(jual, large, ilexuous, with lew and compai'atively large 

 granules. 



The 3'oung 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 verm. 



The differences lietween this species and C. cnnthm are not vei-v 

 striking ; our specimens are, howevei", always smaller, slenderer, and 

 have the columella much less developed. 



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

 si^ecimeu.

A single specimen obtained in fi.S fathoms off Tortugas, with the 

 preceding species, differs from it and from C.fonnosa by its verv luom- 

 inent primary and secondary septa, thus resem))ling the figure of 

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

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

 all otliei' Carvophvlli:v. The descriptions of Duciiassaing and Milne- 

 Edwards and Haime appear to have been made from the same 

 specimen, perhaps an exceptional one.

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