The species is at once known by its remark- 

 ably long, slender, and graceful calycles, with 

 their turret-like opercula. The habit is compa- 

 ratively simple, the primary shoots occasionally

 (Woodcut, fig. 19). 



Hab. On stones, dredged off the Oar Stone, 

 at the entrance to Torbay, in about 10 fathoms (T. II.).
