Hab. “ Very frequent upon the sea- coasts” of Cornwall, Gcertner.

“ The body of this polype is of a light chesnut colour, and feels 
perfectly smooth, though it be lengthways sulcated by a number of 
sulci, that are frequently divided into three smaller ones, and are 
continued into the dentated margin that surrounds the upper peri- 
phery of the body, just beneath the insertion of the feelers. These 
feelers, arising from the disk of the polype, are, according to the age 
of the animal, between 120 and 200 in number ; they exceed the 
body, when expanded, by more than an inch in length, and are of a 
beautiful sea-green colour, except towards their extremities, which 
are coloured with a lively red, like that of the rose. The disk is of the 
same brown colour with the rest of the body, and contains in its cen- 
tre the mouth of the animal, which is an aperture of various shape 
and diameter. —The two varieties of this species, which I met 
with, differ but little from the already described animal. The feelers 
of the one, instead of being green, are throughout of a red colour, 
like that of the mahogany wood. The other variety has pale ash- 
coloured feelers, marked with a small white line running along their 
back ; its body is of the same chesnut colour with that of the first 
species ; but the sulci are not divided, nor has it a dentated margin 
surrounding' its upper periphery.” Gcertner. -—The Act. sul- 
cata of Templeton , which he says is “ most probably the young” of 
Actinia effeeta, Mag. Nat. Hist. ix. 303, can scarcely belong to this 
species. 
2. A. Tuedi,e, body somewhat cylindrical , smooth or wrink- 
led with circular folds ; tentacula numerous , shorter than the 
body , longitudinally striate. G. J.
