 ture narrowly ovate, purple within, its length a little less 

 than half that of the shell; acuminate above. Columella

Somewhat like L. turris Pfr., but* the columella is distinctly 

 convex, the spire shorter, and the apex is decidedly more 

 obtuse. It is also a smaller, less conic shell. The spire is 

 longer than in L. riippelliana Pfr. as figured by Jickeli. 

 The narrow, straight, not branching color streaks are also 

 characteristic. Named for Mr. E. G. Vanatta.
