The coral fleshy, cousisting of a growth of thick contorted 

 laminae with rounded upper edge, the lower part of the lamina and 

 base bare, the upper part with regiilarly disposed polypes with nu- 

 merous small concavities placed at the base on the surface between 

 the polype-cells; the inner part strengthened with thick fusiform 

 longish tubercular spicules with three or five wide smooth, sunken 

 Gross bands, separating the tubercular surface of the middle of the 

 spicules into bands respectively. The spicules in shape like those 

 of Gorgonia setosa and others,

 genera and species of alcyonoid corals in the british mu- 

 seum mit den nachfolgenden Diagnosen : 



Lemnalia n. gen. e fam. Alcyon. Coral soft, fleshy, formed 

 of numerous clustered, small, cylindrical tubes; the outer surface is 

 smooth, distitute of any appearance of spicules, but showing by 

 grooves the places of union of the different tubes that form the mass, 

 each tube ending in a polype. The base is broad , expanded hori- 

 zontally, fleshy like the coral, thrawing up several stems, which 

 are irregularly branched, the lateral branches being saraewhat two- 

 rowed, the terminal branchlets rather clustered, each branchlet ending 

 in a short cylindrical polype, the moutb and tentacles of which are 

 completely rctractile, only leaving a central knob surrounded by 

 eight slightly depressed radiating grooves, and entirely destitute of 

 any appearance of superficial spicules. The whole coral is flaccid 

 and the larger branches appear to be more or lese compressed, but 

 this may in great part depend on the state of the specimen. Sp.

Filigell a e. fam. Gorgon. Coral free, filiform, simple, 

 Blender, rather rigid. Bark thin, transparent, formed of a simple 

 series of flattened, subfusiform, elongate spicules placed close toge- 

 ther side by side, formiug a hard coat; ends blunt, ovate, covered 

 with spicules like the stem. The axis hornlike, slender, cylindrical. 

 Polype-cells short, broad, conical, very far apart, those next, each 

 other being an difi'erent sides of the stem, forming a subspiral series 

 covered with a single series of close spicules like the bark. The 

 cells on each end of the coral are very much alike, and the ends 

 of the coral very similar and covered with spicules; but there 

 does not appear to be any opening for the polype: they are pro-
