We have feen this Sahella as large as a goofe quill, com- ^ 

 plicated, entwined, and interwoven together; andnotlefs 

 than four or five inches in length. Is readily didinguifli- 

 ed from S. Chryfodon by its habits, and by the want of the 

 funnel-fliaped, fibrous mouth ; as well as by its compo- 

 nent parts being more unconne6ledly put together. 



The animal, too, differs effentially from that of the 

 other, efpecially in the more numerous joints of the 

 body, which are not only fwoln, or knotted, but the tu- 

 bercles are remarkably prominent; and a much greater 

 difproportion between the fize of the anterior part, 

 taking in ten or eleven joints, and the reft of the body ; 

 befides, the anterior part of this appears, through a lens, 

 to be punfclured or cancellated.

 fometimes mixed with fragments of (hells, firmly cement- 

 ed together in a rough manner, upon ftones, (hells, and 

 other bodies, in a ferpentine form, and frequently en- 

 twined with So puia triquetra and vermiculans ; to 

 which it is very little inferior in llrength, being by far the 

 flrongefl of all the Sabella tribe. Length two or three 

 inches; diameter one quarter of an inch. Common on
