The whorls are 5J in number, whereof the three or four 

 upper ones are conspicuously small. Perhaps only a variety of 

 p. gibhosa.

This species, the types of which have been kindly si;bmitted to 

 me for examination, exhibits the usual striae of growth, and trans- 

 verse rather remote puncture-lines. The whorls are six in number, 

 slightly convex, and separated by a very oblique suture. The lip, 

 viewed laterally, appears arched and prominent in the middle, and 

 feebly sinuated near the suture. The figure in the ' Journal of 

 Conchology ' represents the body-whorl too convex on the left side 

 and the aperture a trifle too long.

 Shell elongate, slender, semitransparent, pale horn-colour, at 

 long intervals with yellowish stripes marking stages of growth, 

 generally coated with a very black earthy deposit. Spire slender, 

 regular; apex acute, brown. "Whorls 7-8, moderately convex, 

 regularly increasing, divided by a rather oblique suture, bordered 

 above by a very narrow thread-like white line, rather coarsely 

 striated by the lines of increment, which are minutely decussated 

 by excessively fine spiral striae. Last whorl but little inflated, 

 stained witb. rich brown within the aperture at the base of the 

 columella. Aperture narrow, sometimes hardly about as long as, 

 or a little longer than, half the shell ; labrum, viewed laterally,
