GENERAL DESCRIPTION. 
Foeji. 
Base. Adherent to rocks ; little exceeding the column. 
Column. Smooth, or slightly corrugated : studded on the upper half 
with suckers, which form somewhat conspicuous warts. Substance 
fleshy. Form cylindrical; the height often exceeding the diameter. 
Dish. Flat or slightly concave ; the margin scarcely undulate. Outline 
circular. Radii conspicuously marked. 
Tentacles. About two hundred, ai’ranged in four distinct rows ; of 
which the first and second contain each twenty-four ; the third forty-eight ; 
and the fourth, which is marginal, about one hundred. Those of the first 
row, when extended, are about as long as the diameter of the disk ; the 
others diminish gradually, the outer row being small, and often papillary. 
Mouth. Sometimes raised on a cone, which at other times disappears ; 
frequently thrown into lobes. Lip slightly tumid. Throat ribbed. 
Acontia. Emitted freely and copiously. 
CoLoru. 
Column. A light olive drab, slightly varying in intensity ; becoming 
paler towards the lower half, which is often marked with alternate longi- 
tudinal bands of white and drab tint. Suckers whitish. 
Bisk. Opaque white without markings, except that, when full}' ex- 
panded, a grey tinge spreads in a circle, near the bases of the tentacles. 
Occasionally a very faint tinge of yellow suirounds the mouth. 
Tentacles. Pure snow-white, 02 iaque, except when much distended with 
water; without any markings either on the body or around the foot.
