The single example dredged, though imperfect, some of the upper whorls missing, is so 

 entirely distinct from the very few species described of this restricted genus, that I 

 venture to differentiate it. 



From E. tricarinata. Ad. & Beeve, and leptomita, Mel v. & Sykes, it differs both in 

 texture, greater ventricosity of whorl, and especially in the far greater number of 

 revolving spiral cariuse and papyraceous loose longitudinal cancellations.
