Distinguished by the projecting apex and cylindrical form. 

 Except in lacking a columellar fold, this species resembles T< 

 Una.

This interesting species seems distinct from all others of European 

 seas, being well characterized by the formation of the summit. In 

 T. mamiffata Phil., only the first whorl of the spire projects; in T. 

 mariei this whorl is impressed, and the next-to-the-last whorl is 

 prominent (Dautz.').

This large and very interesting species is in too bad condition for 

 satisfactory description. I had called it Utriciiln* uliviinnni* from 

 its shape, which is peculiarly stumpy, with an cxces-i\ ely short and 

 broad mouth, and an unusually high and blunt spire: it is sharply 

 fretted all over with spiral lines, and has a -ti-Mn.i:, little furrow U- 

 hind the sharp-edged twisted pillar. It is like Utrirutu* 

 Gould, or Utrinilw tnctuca Nevill, in its conical >pire. and like
