which have only a single series of plates, from Caryophylliay which may be 

 characterized thus : 



Caryophtlma. 



Char. Gen. 



Polyparium simplex, basi affixum. Corona laminis duplici serie dispositis, 

 <;xterioribus majoribus, regulariter inaequalibus, maximis inter seriei internee 

 laminas interpositis. Discus lamellis erectis, prominulis, foliatis. 

 Type. Car. Cyathus. 



The genus Caryophyllia thus modified contains two recent species*. Car, 

 Cyathus, and the species, the habits of which form the subject of this interest- 

 ing memoir, and which, in justice to the memory of the much regretted natu- 

 ralist who first characterized the soft parts, it is proposed to name 



Caryophtllia Smithii. n. s. 



Car. laminis sub-integris, plicatis, marginibus Icoiter crenulatis ; lamini$ exte- 

 rioribus valde inaqualibus, laminis minoribus tribus inter altiores interpositis. 



Tab. XIII. f. 1 — 6. Mus. Stokes, De la Beche. 



Obs. The plates of the inner series in Car. SmitMi are thinner and broader 

 than those of the same series in Car. Cyathus. 



On looking down with a magnifying glass upon the lamellae which form the 

 papillae in the centre or disc of CaryophylUa, indications of a spiral structure 

 were perceived. This induced Mr. Stokes to make a longitudinal fracture of a 

 specimen of Car. Cyathus in my presence, when the screw-shaped roots of these 

 lamellae were seen running up the centre of the coral parallel to each otlier, 



* It will probably include also^the Car. Europea and Car. pygmeea, Risso, 

 (Hist. Nat. de I'Europe Merid. ;) but the double series of lamellae is not no- 

 ticed, and the figure of the former is not sufficiently defined to decide the point.
