(e) A curious variety (if indeed no more than a 

 variety) of this species has been figured, (f. 4,) from a 

 specimen forwarded by Mr. Bean as Rufilabris? of 

 Leach, which agrees perfectly with specimens collected 

 by Mr. Sylvanus Hanley at Ryde. The shape, as in 

 Parva, is oblong-conical, the 6 or 7 whorls moderately 

 convex, and the lower ones longitudinally obtusely 

 ribbed. Perfect specimens have very fine spiral striae. 

 But the mouth is peculiar. It possesses an extremely 

 thick white marginal callus on the outer lip, which is 

 edged with rufous. The aperture is violet, a smoky 

 shade of which forms the uniform colour of the shell. 

 The rufous arched line which usually ornaments the 

 exterior portion of the lip in Parva, is absent.
