VERMIOLOGY. 



In the Linnaean arrangement it may be be added this species, 

 distinctly appertains to the Echinus tribe. According to Lamarck's 

 system, it is one of his Cidarites : but if described by Lamarck, 

 his description has escaped our reading, although we have sought for 

 it repeatedly in the publications of that author. 



We have received this species from the Atlantic Seas.
