Description. — "Shell slender, extremely elongated, turreted; 

 spire very much elevated and slender; whorls numerous, slightly 

 convex on the surface and very distinctly banded on their lower 

 margin; body volution propoirtionally more convex than the 

 others, being swollen near the middle of its length; attenuate 

 and rostrate below, and nearly or quite one-half the length of 

 the shell as seen from the outside of the aperture; sutures very 

 distinct, bordered by a broad band which is very distinctly sep- 

 arated from the other part of the volution by an impressed line 

 nearly or quite as deep and distinctly marked as the suture line 

 itself; surface of the shell marked by numerous vertical folds, 

 with slightly concave spaces between; the folds are narrow and 

 distinct, and very slightly bent backward in the middle of their 

 length in their passage across the volution, but not interrupted 

 perceptibly at the line separating the band from the body of the 

 volution, and become obsolete on the rostrated part of the last 

 one. Besides the vertical folds, the entire shell is marked by 

 sharp, closely arranged spiral lines, which are finer and more 

 numerous on the upper part, becoming more distant and stronger ■ 

 below, especially on the lower part of the last volution, where 

 they seem to have alternated with finer intermediate stris. This 

 latter feature may be only apparent, however, as the condition 

 of the specimens is not such as entirely to establish this feature 

 as a character of the shell. The crossing of the vertical folds by
