Shell ovate-conical, ventricose, not compressed, of a flesh or 

 pale rose colour; with frequent, transverse, subgranulated, low 

 ridges, the interstices between which are longitudinally striated ; 

 the whorls armed with one row of sharp tubercles, the middle of 

 which are the longest, the other ridges of the body whorl obso- 

 letely tuberculated here and there ; the columellar lip expansive 

 and foliated, and the margin of the outer lip expanded and thin ; 

 the aperture ovate, very strongly and thickly furrowed, of a rich 

 orange colour, and terminating above in a deep foliated sinus, 

 which extends beyond the varix. 



I have been more than usually minute in giving the specific 

 character of this shell, in order to shew upon a comparison with 

 Lamarck's description of Ranella crumena, that the latter is a 

 totally different species. The Ranella crumena is thus described 

 in the Syst. des animaux sans vertebres, vol. 7, p. 151, No. 5.
