Hab. Off south coast of Ceylon, 34 fath. ( f Investigator '): 

 other localities are : — Arabia (Sowerby) ; Japan (A. Adams, 

 Dunker, Pilsbry) ; Mekran coast (Melvill); Darnley Island, 

 N. Australia (Mus. Cuming). 



I am inclined to believe that Tryon is right in considering 

 the S. decussata of Sowerby the same as that figured by 

 Kiener under that name. After carefully comparing the 

 type of S. jimbriolata, a young shell, with this species, I have 

 failed to find any distinguishing characters. 



The shell described by Clessin * as a new species, under 

 the name of S. Sowerbyi, is quite distinct from the present 

 form.

 doubtful whether this species is separable from S. cochlea, 

 Sowerby, said to be from West Africa.
