GENERAL DESCRIPTION. 



Form. 



Base. Adherent to rocks ; considerably wider than column ; outline 

 undulate. 



Column. Smooth, without conspicuous suckers. Substance pulpy. 

 Fomi cylindrical, pillar-like, about twice as high as wide, when extended, 

 but very flat when contracted. Margin a low parapet. 



Dish. Flat or slightly concave ; the margin entire. 



Tentacles. Numerous, arranged in four rows ; moderately long,' slender, 

 and slightly tapering to the tips, their length regularly diminishing from 

 the first row outwards. They are commonly carried sub-erect, the 

 external rows arching outwards. 



Mouth. ? 



Acontia. Emitted from the mouth in some abundance, but not very 

 readily. 



Colour. 



Column. Pellucid whitish. White longitudinal lines are sometimes 

 visible, but they are merely the edges of the septa, seen through the 

 translucent skin, and not bands of surface-colour. 



Dish. Pellucid whitish. 



Tentacles. Pellucid whitish. The foot of each ten- 

 tacle is embraced by two curved lines of dark blue, 

 which approach each other without meeting ; and 

 pass off in front towards the centre of the disk, and 

 behind towards the margin, in the form represented 

 in the accompanying figure. The general effect is to 

 produce a bluish shade on that region of the disk 

 from which the tentacles spring.
