its colour, more globose shape, loftier and more conoid spire, less convex whorls, 
and larger and more rounded ultimate whorl. (See Monogr., pl. xxxi., f. 17). 
The sub-var. spirolineata is described as overspread with black or sienna lines 
on an ochreous ground, ‘‘fondo dorato.” (See Monogr., pl. xxxi., f. 10). 
The sub-var. rufeseens is described as tinged with rufous on a paler ground, 
spiral banding indistinet or absent. (See Monogr., pl. xxxi., f. 13).
