This shell, which has an oblong subfusiform shape 

 that is more produced and tapering above than belovr, 

 is clothed with a dirty olivaceous yellow epidermis, be- 

 neath which it is moderately strong, nearly opaque, and 

 of an uniform white. The very numerous narrow rib- 

 like folds that traverse the shell lengthways, but do not 

 extend to the lower half of the body-whorl, and usually 

 cease towards the outer lip, are somewhat nodulosely 

 decussated by very close-set spiral costellse, which become 

 more prominent and sharply defined on the base of the 

 shell. Of the former, which are slightly but regularly 

 arcuated, and are separated by intervals that are as wide 

 or wider than themselves, we counted about twenty on 

 the penult volution of the delineated example, where 

 seven or eight of the latter were also present. The spire, 

 which exceeds the body in length, and ends in a small 

 and apparently blunt point, is composed of nearly seven 

 turns, that are of slow longitudinal increase, and merely 

 separated by a simple suture ; they are nevertheless very 

 clearly defined from the abruptness with which they swell 

 out from the divisional line, near which they evince a 

 slight disposition to horizontal flatness: the penult turn
