Catalogue of the Marine Shells of Victoria. 193 



As a digest of some of the more important features we cannot 

 do better than quote the remarks made by Mr. E. A. Smith on 

 this species : — " This species varies considerably in form, and the 

 extent of the umbilical callosity, which, however, displays a 

 quite constant peculiarity in being subdivided by a more or less 

 deeply transverse furrow. The umbilicus, too, is much more 

 open in the typical form than in the var. named by Recluz, 

 Natica chemnitzii Colour is of no assist- 

 ance, the chief variation consisting in the intensity of the tint of 

 the aperture and the whiteness of the base."
