 his name, which is prior in date.

Shell oblong, comparatively solid, semitransparent, nearly lustre- 

 less : sculpture consisting of about 20 longitudinal aud somewhat 

 curved riblets on the body-whorl, which are not continued much 

 below the periphery ; each of the two succeeding whorls has 14 to 

 16 similar riblets ; all of these are crossed by spiral riblets or strise, 

 of which there are about 10 on the body-whorl and 4 to 6 on the pen- 

 ultimate aud next whorls ; the topmost whorl is encircled by micro- 

 scopic lines ; the intercrossing of the longitudinal aud spiral riblets 

 does not form tubercles or prickles at the points of junction ; the 

 interstices are square : colour pale yellowish : spire rather slender : 

 whorls 4, slightly convex, the last occupying two thirds of the spire ; 

 apex blunt: suture distinct, but rot deep: month more round than
