Differs from the type in the colour being of a very much lighter 

 shade, the apex, however, being of the usual dusky tint; the .shell 

 is also more ovate and shorter, and the lamina is slighth' more 

 horizontal. I had proposed to describe this shell as a new species, 

 but a few specimens of the variable^, simularis show a slight 

 approximation, and it will, I think, only prove to be an extreme 

 variety.
