 VOLUTA elevata. 



TAB. DCXlU.—fig. 4. 



Spec. Char. Elliptical elongated ; transversely stri- 

 ated, costated ; spire produced ; the whorls con- 

 vex, their upper parts deeply furrowed and 

 crowned with rows of small spines between the 

 furrows. 



1 HE elongated spire distinguishes this from all the Vo- 

 lutes which approach it in general appearance. 



Found by Mr. Wetherell at the Railroad, near Camden 

 Town ; it is rare.

 the upper edges of the whorls crenated ; the 

 suture defined ; columella many-plaited, the 

 three lower plaits large, the last but one largest; 

 aperture oval, truncated at the base.

This Volute appears to vary in form with its locality. The 

 English specimens have the costae obtuse, and gradually 

 lost towards the base of the last whorl, while in those from 

 Grignon the elegantly curved costae are sharp and complete 

 to the very edge of the aperture. The fine striae which cross 

 the ribs are also more conspicuous in the British variety. 

 The lip is thickened when full-grown in both. 



A rare shell at Barton. I am indebted to Mr. Lowry 

 for the only specimen I have seen.
