As a work of Prof. Sars on the arctic raollusca on the 

 Norwegian coast will soon be published, I will not anticipate 

 the description of this species. It will be illustrated on his PI. 17.

This form has been found in Finmarken by Prof. Sars and 

 will be described in his above mentioned work. It approaches 

 closely to the B ßmiiarlxianuni Verkr., but is distinguishable by 

 its more tumid whorls, and its comparatively shorter spire. 

 According to Sars the nucleus in the operculum is central.
