THE VESTLET. 275 



tentacles "0^;" but what the integer is to which these 

 fractions refer we are not informed. There is doubtless 

 some error, as in the description these organs are called 

 " long; " and the figures, which are rude enough, are said 

 to be " of the natural size," and these represent the animal 

 as 1£ inch in length, with the tentacles, both marginal and 

 gular, about I of an inch. A slender cylindrical column, 

 Avith a trumpet-shaped margin, a funnel-shaped disk, two 

 kinds of tentacles, and a slit-like mouth, — this animal 

 possesses in common with the Ceriantlius. It is repre- 

 sented, indeed, as standing erect, with the base attached 

 in the manner of an Actinia : but this was probably drawn 

 from assumption, and the attachment may have been 

 similar to that which I have described in other Ilyantkidce. 

 Professor Forbes says the base was "not expanded," which 

 favours this supposition. No tube or case is alluded to, 

 but it may be that this is developed only at a later period 

 of life. The specimens were dredged in fifty fathoms in 

 the Shetland Seas ; the column was greyish pink; the disk 

 and gular tentacles white ; the marginal tentacles fulvous. 

 It gave out a vivid phosphorescent light when irritated in 

 the dark.
