We have never as yet obferved this, but in one branch 

 of the inlet that runs up to Kingsbridge. It is the tube 

 of Terebella cirrata, and as it has not, we believe, been 

 defcribed as Engiijh, and pofleffing as much claim to a 

 place in the SabcUa genus as many others., could not be 

 omitted. 



The animal is furnifhed with two feries of tenlacula or 

 feelers, thofe on the upper lip, or round the mouth, are 

 extremely numerous, long, filiform, and of a pale co- 

 lour; thefe ufually contraft into curls: the others, fitu- 

 ated behind the head, are alfo numerous, fliort, flrait, 

 branched, and of a reddidi fledi-colour : the body, when 

 extended, is nearly a foot in length ; the annulations, 

 about ninety, furnidied, as ufual, v^'iih. fafciculi and 

 branckice ; the tubercles very prominent, but the joints 

 not tumid as in the animal of 5. conchiLega : colour pale, 

 inclining to purplifh-brown on the upper part near the 

 head: when bruifed difcharges a red liquor. 



When drawn from its cafe, it becomes confiderably 

 larger in the anterior part of the body, than the bore of 

 the tube, but tapers greatly towards the tail. 



This clafs of amorphous animals will, in all proba- 

 bility, ever remain in great obfcurity ; the great fimi- 

 litude of many, their variable forms, and different ap- 

 pearances in the living, and the dead flates, efpecially 

 when preferved in fpirits, will always occafi-on great 



difficulty in difcrimination.
