I have seen a shell, which was said to be the young of this 

 species, of a yellowish-brown colour, ornamented with several 

 bands formed of white arrow-shaped or heart-shaped spots. It 

 is probable that this may hereafter prove to be a distinct species. 



This species is somewhat similar to the preceding, but it may 

 be instantly distinguished from it by its smaller size, lighter 

 colour, and its ornamental rows of small brown spots, one of which 

 is near the suture, and the other at the front extremity of the last 

 "whorle. Lamarck has corrected, in his excellent history, the 

 confusion which he had previously created between this and the 

 preceding.

Shell oblong-ovate, white, with three obscure broad flesh- 

 coloured bands, and marked with very narrow yellow longitudinal 

 lines, which are often concurrent; the base is white, rather con- 

 vex; the edge is thickened and slightly margined, especially on 

 the outer side and front extremities ; the teeth are white, rather 

 distant, and slightly produced over the lips ; the columella front 

 very slightly concave, plaited ; spire concave, partly covered up ; 

 inside white : axis J'q^, diameter Jjj of an inch. 



This shell appears to have been involved in obscurity since the
