tentacles 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 inch in length, with the tentacles, both marginal and 
gular, about I of an inch. A slender cylindrical column, 
with a trumpet-shaped margin, a funnel-shaped disk, two 
kinds of tentacles, and a slit-like mouth, — this animal 
possesses in common with the Cerianthus. It is repre- 
sented, indeed, as standing erect, with the base attached 
in the manner of an Actinia ; but this was probably di'awn 
from assumption, and the attachment may have been 
similar to that which I have described in other Ilyanthidce, 
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.
