In this species the pad on the spire is generally much heavier than it is on Ancilla australis, 

 though this is not a constant characteristic, but the spiral striolations are stronger and more fretted 

 than they are in that species. Weinkauff, in the Conchologische Cabinet (loc. cit. supra), says of 

 Ancillaria mucronata that it is " von A. montrouzieri in der Schale wenig verschieden ; " but that is 

 hardly the case, for the shell in the former is shorter, the callus in front is wrinkled, and the colour 

 is dirty.
