Body yellowish-white, often transversely brindled with 

 smokecoloured lines : snout projecting beyond the foot, cloven 

 in front, ileshcolour or pink on the upper part : tentacles club- 

 shaped, sparingly setose in some specimens and smooth in 

 others, marked internally down the middle by a brownish

 scarcely raised, sometimes encircled by a bright sulphurco- 

 louredline : foot lanceolate, short, rounded in front and behind ; 

 tail very slightly bifurcated : opercular lobe dark -purplish- 

 brown.

 parent, and glossy: sculpture, apparently none, but under a 

 good magnifier consisting of a few indistinct spiral striae : colour 

 dark-red, claret, yellowish -brown, or tawny : spire bluntly 

 pointed : whorls 5|, compressed, gradually enlarging ; the last 

 occupies three-fifths of the spire : suture slight, having fre- 

 quently a dark band below it on each whorl, caused by the 

 double layer of shell in that part : mouth rather small : outer 

 lip slightly incurved at the upper angle, thickened in full- 

 grown specimens, and spread out at the base : inner lip re- 

 flected on the pillar, and united with the outer lip, but not 

 so as to form a distinct peristome : operculum dark- crimson,
