2, form purpurascens Pfr. Dull purple, the aperture and 

 lip violet, <common (fig. 3). 



3, form bipartita. Upper surface rose (fig. 4) or purple 

 (fig. 5) base pale yellow, the lip white. " Frequent in the 

 metropolis of the species but very rare elsewhere ' ' ( Garrett) .

 end of penultimate whorl to straw yellow or corneous on the 

 last whorl; apex whitish; mouth and lip white (figs. 6, 7).
