Shell oblong, ovate, fulvous brown, ornamented with crowded 

 white spots and eyes, the eyes surrounded with a bright brown 

 ring, which is usually thicker on the lower side ; margin slightly 

 thickened on both sides, violet, spotted with a few scattered 

 smallish purple spots ; the upper part of the sides of the front end 

 obscurely pitted ; base white or rose-coloured, nearly flat ; aper- 

 ture rather wide ; lips rather thick ; teeth small, with grooves not
