Shell with spiral lirae much more numerous, (35 at all), having in many places the 

 character of being split by an intermediate groove; brown colour more intense, forming 3 zones 

 of blotches, one row of smaller ones just below the shoulder, another of larger flames above 

 the centre and a similar broader one near the base, the intermediate zones with spiral rows of 

 brown points, on the most basal part the colourmarkings consist of larger points.

I have been in doubt, whether I should describe this shell as a new species or not. By
