GENERAL DESCRIPTION. 
Form. 
Base. Adherent to rocks, but readily detached. Considerably exceeding 
the column. 
Column. Smooth, slightly corrugated in contraction ; with distinct 
suckers on the upper half. Subsstance fleshy. Form cylindrical; capable 
of great elongation, in the shape of a tall and slender pillar. Margin 
tentaculate. 
Dish. Flat; the margin plane. Outline circular. Radii distinct; crossed 
by fine stria). 
Tentacles. About two hundred, arranged in five rows ; of which the first 
and second contain each twelve, the third twenty-four, the fourth forty- 
eight, the fifth ninety-six. Those of the first row are longest ; but there is 
not so much difference between the rows in this respect as is the case with 
the preceding species : those of the first row, when fully extended, are 
longer than the width of the disk ; all are slender, tapered to a fine point, 
and very flexuous. They are usually carried either arching downwards 
on every side or sub-erect, and thrown into many irregular snaky curves. 
Mouth. Set on a low eone. Lip thin ; slightly furrowed. 
A contia. Emitted from various parts of the body, from the base to the 
summit, occasionally ; but very reluctantly, and in small quantity : short 
and slender.
