There can be but little doubt that the shell figured by Chem- 

 nitz, and Muller's L. tulipa are the same, and the former is 

 said to differ from C. tintinnabulum, which it otherwise re- 

 sembles, in being of a paler colour, much smoother, and in 

 having the interstices marked with longitudinal instead of 

 transverse stria;. The present species is an inhabitant of the 

 North Sea, and L. tintinnabulum is found only in warm 

 climates.
