" Shell ovate, reddish-brown, or ivarely pale brown ; the spire 

 prominent, covered; the base convex, white; the margin slightly 

 thickened, rounded, with small, round, black spots; that of the 

 inner lip rounded, only slightly extended; and that of the outer 

 rather sharply edged, with the extremities generally dark; the 

 aperture rather large; teeth equal, small, close; columella rather 

 concave, and rather deep, plaited nearly the whole length; inside 

 pale brown. Axis i^, diameter ^^ of an inch." 



" This shell has not been taken notice of by any of the French 

 writers, although it is not uncommon in old collections. It varies 

 sometimes in being of a very pale yellowish brown." 



Figs. 1, 2, 3, of PL xxi., represent examples of what I propose 

 to call the typical group of this very variable species. 



The specimen represented on PI. xxi., fig. 1, measures from the 

 syphonal end to the posterior apertural notch 31 mm., 22 mm. 

 wide, and 18 mm. high, i.e., from base to dorsum; and is one of 

 the finest specimens of the species I have seen. Colour deep 

 chocolate, base bluish-white showing very few spots on the base; 

 the slight dorsal sulcus is covered with chocolate spots on a lighter 

 ground than the dorsum; spire deeply sunk; on the right colu- 

 mellar margin there are 27 strong white teeth sloping into the 

 aperture; the teeth on the left point directly to the aperture, and 

 do not show on the base. 



Fig. 2, PI xxi., is that of a specimen measuring from the 

 syphonal end to the posterior apertural notch 26 mm., 17 mm. 

 wide, and 13 mm. high from base to the most prominent part of 

 the dorsum. Of a lighter chocolate colour than the preceding 

 example on the dorsal surface; there are two indistinct bands of 

 a darker colour across the dorsum, which are found in many of 

 the varieties of this species; there is a very distinct dorsal sulcus 

 covered with dai'k chocolate spots; in looking down on the dorsum 

 the spots can be seen on both sides; spire not so sunk as in the 

 preceding example; on the right columellar margin there are 23 

 strong teeth sloping into the aperture ; on the left side the 

 teeth are finer and do not show on the base, which is of a 

 bluish colour.
