GENERAL DESCRIPTION. 

 Form. 



Base. Adherent to rocks ; expanded beyond the column. 



Column. Smooth, without conspicuous suckers. Substance pulpy. 

 Form cylindrical; the height in general slightly exceeding the diameter. 



Disk. Flat or slightly concave ; the margin entire. Outline circular. 

 Radii distinct. 



Tentacles. About forty-eight, arranged in four row3 ; of which the first 

 and second contain each eight, the third and fourth each sixteen. Those 

 of the first row are by far the largest, the size diminishing regularly to the 

 external row : their form is stout and conical. They are usually spread 

 horizontally, and have their tips frequently bent downwards. 



Mouth. Raised on a conspicuous cone, which, however, is not per- 

 manent. Lip capable of great protrusion and distension. 



Acontia. Emitted freely and copiously. 



Coloub. 



Column. Marked longitudinally with many bands and narrow lines of 

 opaque white, separated by interspaces, always narrow, of pale semi-pellucid 

 brown, or drab. The summit is occasionally tinged with reddish-brown. 



Disk. Opaque white, marked with five radiating lines of pellucid white. 

 The tentacular region is marked with the ring-lines to be presently 

 described. 



Tentacles. Ivory white, without the least appearance of spots or bars : 

 but at the very foot, where each tentacle springs from the horizontal disk, 

 it is surrounded by a narrow ring of purplish, reddish, or dusky brown.
