GENERAL DESCRIPTION. 



Form. 



Base. Adherent to rocks and shells ; generally broader than column ; 

 its outline sometimes slightly undulate 



Column. Pillar-like, very variable in height and shape ; the margin 

 forming a distinct parapet or terrace, crenated within, but not separated 

 from the tentacles by a fosse. Surface smooth, or slightly furrowed, 

 lubricous. Substance pulpy, transparent. 



Disk. Circular, never waved, often greatly exceeding the column, flat 

 or slightly concave ; smooth, with the radii marked, but no gonidial 

 distinction. 



Tentacles. Upwards of 100, set in four rows,— 16, 24, 32, 32, = 104 ; 

 the outer rows largest ; each composed of a more or less pillar-like or 

 conical stem, and a globular head : in the inner rows, the stem is very 

 short, and the head nearly sessile. The outer rows usually diverge 

 upward and outward, projecting over the margin, and not seldom hang 

 downward. 



Mouth. Protrusile at pleasure into a truncate cone or cylinder, sur-
