This is without doubt the original Auris Sileni of tin- 

 Vienna Museum, of which a characteristic representation 

 is given by Born and Chemnitz, and not the shell des- 

 cribed by Lamarck under the name Auricula Sileni. It is 

 a short thick shell of tumid growth, distinguished by a 

 remarkably prominent plait on the columella and bold 

 oval aperture with rudely reflected lip.
