 Hab. Parasitical on sea weeds, corallines, stones and dead shells, 

 at and within low-water mark. " On the shore of the island of Bur- 

 ra, and on the Holm of Cruster, in Bressay Sound, in Shetland,"

 Island of Bute, Dr Coldstream. Maybole, Ayrshire, Rev. George

 House Point, Belfast Lough ; Aug. 1807," J. Templeton, Esq. In 

 Berwick Bay, not uncommon. 



Polypes in general gregarious, fixed by a narrow disk, from two to 

 six or eight lines in height ; clavate or cylindrical with a knobbed 

 head, rose-coloured or wliite, smooth, fleshy ; the head or upper part 

 furnished with from 5 to 25 scattered filiform tentacula, which are 

 usually much shorter than the body, and not always of equal lengths. 

 In gravid individuals the oviform gemmules hang from the bases of 

 the tentacula in one or several clusters ; they are of a round or el- 

 liptical figure, rose-coloured with a darker centre, and large in pro- 

 portion to the animal. 



Towards the roots of the tentacula we can frequently observe a 

 reddish spot which probably indicates the position of the stomach ; 

 and a dusky line prolonged down the centre of the body appears to 

 show that the latter is hollow, the canal being doubtless intestinal. 

 The tentacula are also tubular, as I infer from their being marked 

 with a similar line : unlike those of the Hydra they are smooth, or 

 merely crenulate, but like them they are capable of being shortened 

 and elongated at will, though to a less extent. The form of the body 

 is also varied at pleasure, but all its motions are slow, and indicate a 

 very inferior degree of irritability. I have never been able to disco- 

 ver a mouth or aperture on the top on the body, but Dr Coldstream 

 says, " after having been kept in small vessels of sea-water for some 

 hours, without renewal of the water, some of the animals protrude 

 the inner surface of the mouth, so as to present a convex disc, with 

 the tentacula ranged round it." — The young are of a fine pink or rose 

 colour : at first they resemble little smooth rounded tubercles, which 

 gradually elongate, and soon acquire one, then two, three or four 

 tentacula, and so on imtil the number of maturity is completed, for 

 these organs are developed in succession.
