" The shell with animal was placed in spirit, but has been 

 unfortunately lost ; it was thin and glass}*, with about 4 w 7 horls. 

 I however made a careful drawing of the animal at the time it 

 was taken." Animal dull purplish gray; mantle-lobes, which 

 can cover the entire shell, are very niiiiutel}^ mottled, finely 

 papillate ; posterior margin with three wart-like processes on 

 each side ; posterior part of foot with diagonal parallel ribs ; 

 edge of foot with a distinct marginal line. The mantle is divided 

 into three lobes, one of rectangular outline is on the anterior 

 left margin. The shell w r hen the animal is in motion is very 



slightly exposed.
