GENERAL DESCRIPTION. 

 Form. 



Base. Adherent to rocks ; considerably exceeding the column. 



Column. Flat and wrinkled when completely contracted : rising to a 

 tall, somewhat slender pillar, studded with low warts on its upper portion, 

 but covered on its lower two-thirds with a tough, firmly adherent epi- 

 deraiis, the upper edge of which is free, with a ragged foliaceous margin, 

 not forming a tube. The surface of this is transversely corrugated, but 

 not warted. The animal frequently expands in its low condition, when 

 the flower occupies the summit of a very low cone, and is not half the 

 diameter of the base. A slight margin, much wrinkled in semi-contraction, 

 and forming a star of radiating furrows in closing. 



Disk. Flat or slightly concave ; outline circular. 



Tentacles. Arranged in five rows, viz. 6, 6, 12, 24, 48 = 96 ; short and 

 slender, diminishing from the first row outwards ; in ordinary extension 

 not longer than one-fourth the diameter of the disk ; generally carried 

 arching over the margin, the tips occasionally turned up. 



Mouth. Elevated on a strongly marked cone. 



Acontia. Not emitted, even under strong irritation, while in my posses- 

 sion. Mr. Brodrick, however, has seen them projected from the mouth.
