Coral clavate ; stem thick, contracted below ; outer surface 

 coriaceous, granular; skin of branches thin, studded with 

 large, opaque, fusiform spicules. Upper part divided into 

 short, conical, spreading branches, closely covered with sub- 

 cylindrical incurved polype-cells.

c. Coral soft, membranaceous, cellular, smooth, with the polypes at the 

 ends of the fleshy branches. Polypes partly retractile, leaving a 

 subspherical terminal head to the branchlets • a few imbedded, 

 spicules near the mouth and in the tentacles. Lower part of the 

 coral simple or retractile into a tubular spinulose sheath. 



Fain. 11. LemnaliacUe. 



Coral simple at the base ; stem formed of the clustered 

 cylindrical tubular bodies of the polypes ; outer surface smooth, 

 without spicules. 



Known from Nephthyadce by the polype-cell being pedi- 

 celled, and the stem and branches of the coral not being co- 

 vered with superficial fusiform spicules.
