 DESCRIPTION. 



Shell of a conical, turreted form, sometimes rather 

 corpulent, and again quite slender, the last whorl be- 

 ing much less ventricose in proportion than the upper 

 ones, rather thick in substance ; color, when young, pale 

 yellowish green or drab, becoming bleached or gray with 

 age, the interior, however, sometimes having the bright 

 yellow of yolk of egg, and always more or less tinted 

 thus when living, becoming at last dead white ; surface 

 irregularly and loosely wrinkled ; whorls four, forming a 

 well-proportioned spire, the upper ones well rotinded, 

 and separated by a deep suture, the apex acute, colored 

 yellow ; last whorl conical at its upper third ; aperture 

 ovate, rather more than half the length of shell, the lip 

 somewhat incumbent ; columella without a fold, rounded, 

 its edge above being seen winding far within the spire. 



Length, half an inch ; breadth, one-quarter of an inch-
