The sculpture varies somewhat in prominence. Usually the spiral striae are 

 more or less deeply impressed and crossed by fine longitudinal lines of growth (forma 

 typica). Sometimes the longitudinal lines have the shape of fine lamellae and are as 

 conspicuous as the spiral sculpture itself, which consists of broader and very shallow 

 furrows, sometimes limited by fine lamelliform riblets (var, gigantea). 



The colour is pale yellowish, iridescent, to grayish green and dark bluish, 

 Var. gigantea is always light-coloured.
