' Probably only a variety of tenehricosus. 



- Fischer changed the name jj/icahts to clessini because the former name had been 

 used by Sowerby for a species which he (Sowerby) placed in Mycetopus. Sowerby's 

 shell is a Mutela, and that of Clessin a Glaharis of the 'Tenehricosus group. Von 

 Ihering applied the name nehringi to the above after Fischer had changed it, and 

 was evidently not aware that the French savant had given it a new name.
