are pure white. Whorls seven or eight, slightly ventricose, 

 uniformly spirally lirate, the interstices when viewed with a 

 lens being beautifully decussate. Mouth wide, outer lip thick- 

 ened, transversely striate, as are the whorls, columellar margin 

 simple, canal short, wide. About ten or twelve specimens. 

 (lone from tov a violet).

In marking, this small species is a little like the well-known 

 D. vidua Reeve, in comparison to which it stands a veritable 

 pigmy. Two forms have been seen by us, differing in colour as 

 follows : — In what would be considered the type, an ashy 

 brown is the prevailing hue, filletted round the whorls trans- 

 versely with bluish white ; in the other, a handsomer variety, 

 a warm ochre with flecking and median brown linear banding 

 round the three last whorls, which are seven in number alto- 

 gether. Form oblong, very solid, obtusely ribbed with fine 

 spiral striolations, outer lip extremely thickened, inner simple. 

 (de/xepioTTLs, grave, sedate, from the sombre appearance).
