motion for a long time, they are apt to be mistaken for independent and perfect worms, 

 which they much resemble.

L. octo-radiata, Lam. Hist. Nat. ii. 474. 



Hab. Berwick Bay, rare. 



Peduncle short, sub-angular, dilating into eight equal oblong arms, each terminated by a 

 globose tuft of filaments, tipped with a gland. The arms are mottled with two rows of 

 spots, produced by the opacity and configuration of the internal viscera ; and they are 

 connected together by a transparent membrane. Between each of them there is an oval 

 vesicle placed on the edge of this membrane. Within the stalk there is a tube which, pro- 

 longed, seems to form the mouth, of a square shape, projecting in the centre of the arms. 

 The colour of our specimen was a clear, fine red : it was three-quarters of an inch in height, 

 and, when expanded, the diameter was about one inch.
