Th« fine example from which our £gure of this rare and inter- 

 esting Volute is taken, once held a distinguished place in the 

 Conchological department of the celebrated museum of Sir Ashton 

 Lever. The length of this shell is four inches and one eighth, its 

 greatest breadth two inches a»d fcee eighths ; the <?olow a kind 

 of buff with an olivaoeous tint, and the whole surface traversed 

 with a number of irregularly undulated or zig-zag Hnfes 'of Amk 

 brown, disposed longitudinally throughout : "the peculiar tjhaf^cter 

 of which will be conceived more readily from l3re deliai-efiticai 

 than from any explanation that can be conveyed by words. These 

 longitudinal lines are numerous upon 1^e back or superior surface 

 of the first wreath of the shell, and extends also on the lower surface 

 as far as the dilated space of the columella or pillar lip ; which 

 latter is of a pure white and destitute of any markings. The mouth 

 or aperture with the interior of tire sh^ll is also white, and thfe 

 pMts of the pillar, which constitutes one of the most essential 

 characters of the genus Volute, are prominent and well defined.
