whicli is highly interesting, as presenting a link which 
connects Sagartia with Actinia, The disk and tentacles 
are exactly those of meseinhryanthemum ; and the texture 
of the column, and its style of colouring, arc such as to 
give the impression that the most familiar of our Actinioi'ds 
is before us. Yet, on examination, the perforation of the 
integument, the presence of acontia, and the absence of 
spherules, indicate its place among the Sagartiadee. At 
the same time, its indifference to contact, and its permanent 
expansion, — for it seems not to have the power of retracting 
the tentacles, — are peculiarities which ally it to the mem- 
bers of the following family. 
I have seen but a single specimen, which may be im- 
mature. The specific and English appellations allude to 
the perforations of the column-wall, which are very striking. 
It attaches itself readily by the base ; is constantly swell- 
ing out part of its body in lobes ; and generally remains 
wddely expanded, with the tentacles arching outwards and 
doAvnwards. It feeds eagerly, and appears quite hardy in 
captivity.
