Profs. V. Martens and Hutton do not appear to have noticed 

 this form, so admirably represented by Philippi. In colora- 

 tion it much resembles L. diemeneyisis and has been confounded 

 with it by some authors ? The shape is quite different, the 

 spire being more elongately produced, &c. In some respects 

 it also resembles Reeve's figure of L. Icevis. It is smoother and 

 more regularly pyramidical, &c., than the preceding.
