GENERAL DESCRIPTION. 
Form. 
Base. Adherent to holes in rocks, frequently detached : somewhat 
exceeding the column. 
Column. Smooth towards the base, but beset on the upper two-thirds 
with suckers, which have a strong power of adhesion. Substance firmly 
fleshy. Form cylindrical and much lengthened, in full extension, the 
height many times exceeding the diameter. Margin tentaculate. 
BisTc. Flat or slightly concave : the margin rarely undulate. Outline 
circular. Radii strongly marked, and crossed by close-set transverse striae. 
Tentacles. Numerous (amounting to two hundred or upwards in some 
specimens), arranged in four or five rows ; the first row largest, and 
decreasing gradually to the outermost ; in extension about as long as the 
width of the disk, conical, bluntly pointed. The manner in which they 
are carried varies in the diflSerent varieties. 
Mouth. Generally elevated on a cone.
