OBSERrATIOKS. 



This beautiful species was presented to me by the late 

 Mr. Stephen Elliott of Charleston, S. Carolina, as an inha- 

 bitant of the west coast of Mexico. The coloured lines 

 on the anterior part of the shell, are somewhat like those of 

 V. geographica, Gmel., but these lines have a bluish shade 

 forwards, are more regular than in the figure of that species 

 in the Encycl. Meth., and as a species it is widely distinct.. 



1 have an indistinct recollection of a figure resembling 

 this species, but I cannot recall the work, for the purpose 

 of comparing the characters.
