S. CINEREA Watson. PL 20A, figs. 49, 50. 



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

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

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

 emarginate 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 then 

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

 flat raised surface of the shell between is from one to three times 

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

 wanting ; on the third whorl only one appears close below the 

 suture. Color porcellanous and glossy white, with three n a rro wish- 

 grey bands, made up of small, cindery, somewhat longitudinally 

 arranged spots ; these bands, absent on the earlier whorls, first make 

 their appearance on the fifth, from which to the seventh there 

 only one band immediately above the suture; its upper edge is som< 

 what indefinite, flame-like expansions of it extending upwards he] 

 and there. On the body another similar band 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 first; the 

 cindery spots forming these bands are entirely absent in the fui 

 rows. Spire short and conical ; apex small and sharp, the minute ti] 

 being distinctly prominent and not in the least twisted or inverted. 

 Suture slight, being scarcely impressed ; in the earlier whorls it 

 very horizontal, but latterly it is oblique. Mouth long, narrow, 

 curved in toward the axis of the shell, sharply pointed above, 

 channelled in front of the pillar point. Outer lip sinuated above 

 lip edge roundly prominent at the periphery, where it is patulous, 

 hardly curved, and in direction oblique. On the base it is extremely
