DESCRIPTION. 



SHELL small, elongated, turreted, transparent, with 

 delicate, longitudinal striae, sometimes of a spermaceti 

 white, and sometimes wax-yellow. Whorls about eight, 

 convexly rounded, revolving more closely at apex than 

 elsewhere, so as to form a somewhat obtuse summit, the 

 last whorl less than one-third the length of the shell ; 

 suture deeply impressed, aperture elongated, narrow, 

 rhomboid-elliptical ; lip simple and regularly curved ; 

 columella nearly straight, reflexed, protecting a minute 

 umbilical perforation. 



Length of axis nearly half an inch ; diameter about 

 one-tenth of an inch. 



GEOGRAPHICAL DISTRIBUTION. Found in Florida 

 abundantly, under fallen leaves, and also in most of the 

 West India islands.
