but they want the carinated edge, and have every other ap- 

 pearance of belonging to this species. It has been already 

 remarked, that S. intricata is not distinct, and S. reversa of 

 Montagu appears to be only a reversed Variety of this 

 species. 



TUBULARIA. 33. Shell taper, subulate, and flexu- 

 ose, with the larger end detached and as- 

 cending. 



Serpula tubularia, Montagu Test. p. 513. Maton and 

 Racket, in Lin. Trans, viii. p, 244. 



Inhabits the coasts of Devonshire on Shells. Montagu. 



The larger end of the shell is frequently detached for half its 

 length, and ascends at a considerable angle, wherein it prin- 

 cipally differs from S.vermicularis, which is usually attached 

 to some other substance throughout its whole length. Ac- 

 cording to the observations of Mr. Montagu, the animal of 

 this species is an Amphitrite, and in S. vermicularis it is a 

 Terebella. 



DENTicuLATA. 34. Shell taper, subulate, nearly 

 straight, with the sides toothed, and a longi- 

 tudinal glabrous rib in the middle.
