 Terebella conchilega. Turt. Lin. iv. p. 84. 



S. compofed offinefand, agglutinated together into 

 a thin, brittle tube, without any membranaceous internal 

 coating. Length two inches or more : diameter at the 

 larger end three-eighths of an inch, gradually tapering 

 to half that fize at the fmaller end. 



This is not uncommon upon many of our fine fandy 

 fhores. 



Great confufion has arifen with refpe61. to the fyno- 

 nyms of this Sabella: Gmelin has given it firfh under 

 the article Amphitrite, quoting Martini, tab. 4. f. 26. 

 27. and afterwards as a Sabella, with reference only to 

 the 27 fig. of that author. 



Do61or TuRTON has given it an additional place in 

 the genus Terebella, with reference to the Sabella tubi- 

 Jormis of the EritiJJi Zoology ; and Mr. Pennant has 

 given the animal as Nereis conchilega. 



The animal is certainly the Amphitrite auricoma as 

 defcribed by Gmelin, and is generally known by its two 

 rigid, gloflfy, gold-coloured, briftly tentacula.
