The entire surface of the shell is covered with irregular and super- 

 ficial striae, which enlarge little by little with the growth of the 

 shell. Besides these, the lens shows other excessively fine, wavy

 spire. The color of this Bulimus offers much analogy with B. tham- 

 noicus var. marmorata [B. alauda\ ; on a ground of flesh tint, tinged 

 visibly with fawn, there is a pattern of a multitude of transverse 

 short lines of a reddish or purplish color, sometimes united into con- 

 tinuous zones, sometimes producing by their irregular disposition an 

 agreeable dappled effect. (Morel.').
