 Nassa reticulata L. Anglesea, &c. 

 N. reticulata L. var. Southampton. 

 N. reticulata L. var. nitida, Harwich. 



Jeffreys "with some misgiving" gives it as N. nitida. 

 It is shorter, stumpier and broader for its size than the 

 type, more lustrous, the longitudinal ribs are stronger 

 and not nearly so numerous, while the spiral ridges are 

 fainter; thus the shell has not the tesselated appearance 

 characteristic of the type.

 N. incrassata Miill. var. Scarboro'.
