Shell. — Fusiform, narrow, finely ribbed and spiralled, with a high, conical, subscalar,

 Sculpture : There are fine sharpish riblets parted by furrows of twice their breadth, which 

 run pretty continuously with a slight twist to the left from whorl to whorl ; there are about 

 eighteen or twenty on the last whorl, and fewer on each preceding whorl ; they are a little 

 oblique, and sinuous on the base ; they originate below the sinus-area and run down to 

 the inferior suture ; on the base they become finer and more crowded, and gradually die 

 out without reaching the snout ; the lines of growth are shown by fine close-set scratches. 

 Spirals — immediately below the suture there is a broadish depressed band constituting the
