Shell strong, oblong, pointed at both ends, white with three spiral 

 bands of eindery spots; a high, conical, sharp-pointed spire, barely 

 convex spirally striated whorls, a slight suture, a long narrow mouth 

 emarLfinate in front, and a strongly twisted double toothed pillar. 

 Sculpture : Longitudinals there are fine, approximate, hair-like, 

 obsolete lines of growth. Spirals there are shallow square-cut 

 furrows formed of small contiguous oval pit-marks; of these there 

 are on the penultimate whorl about 8, on the body about 25 ; the 

 flat rai^d >urface of the shell between is from one to three times as 

 wide as the furrows. On the first two whorls these furrows are 

 wanting: "" the third whorl only one appears close below the 

 suture. Color porcellanous and glossy white, with three narrowish- 

 l.aiiiU. made up of small, cindery, somewhat longitudinally 

 arranged spots; these hand-, ah>ent on the earlier whorls, first make 

 nee on the fifth, from which to the seventh there is 



only one land immediately above the suture: its upper edge is some- 

 what indefinite tl;mi- like expansions of it extruding upwards here 

 and tli. r .-. ( )i\ the body another similar hand occurs at the periph- 

 ery ; and a third is on the base originating just above the upper 

 pillar-tooth: the two latter are more defined than the tir>t : the 

 niriL r these bands an- entirely alrnt in the fur- 

 rows. Spin- -hort and conical : apex -mall and sharp, the minute tip 

 iv prominent and not in the least twi-ted or inverted. 

 Sdture slight, being Scarcely impressed; in the earlier whorl- it is
