We have, with some slight hesitation, followed the 

 opinion of Loven, Jeffreys, and Alder, in regarding this 

 shell as identical with the rufa of Philippi, although it 

 differs in some minor particulars. The Mediterranean type 

 presented to us (unfortunately the last whorl was broken 

 away) by the author of the species is rather more slender 

 and solid, has the ribs, which are twenty-three in number, 

 quite straight, the volutions quite flat, and the colour 



* At least, it agrees better with this than with any other of our known Clicm- 

 nitxice (and assuredly it belongs to that genus). Montagu, in addition to his 

 brief description, remarks, that it resembles degantissima, but is less slender, and 

 has fewer and more distant riblets, that are not slanting, but arched, and with 

 broader intervals. Laskey is said to have taken the shell from the shore of 

 Jura. 



" Slender, white, with eight or nine volutions, furnished with fourteen ribs or 

 elevated strite ; these stand straight in the line of the shell ; apex pointed ; base 

 destitute of stritc; aperture subovate. Length three-eighths of an inch." (Mont.)
