The species oliva Linne cannot be ignored, in the light of 

 our present ruling in nomenclature ; while a composite species, 

 the prevailing form is readily recognized as Hanley in his "Shells 

 of Linneus " page 215 says : "Still it is not unworthy of remark 

 that the Oliva nigrita of Karsten (0. maura of Sowerby, Genera 

 Shells) has been indicated as the principal variety or form in 

 the 'Museum Ulricae' and that all cited engravings (Argenville 

 alone excepted) of the tenth edition of the 'Systema' wherein 

 the species originally appeared, pertain to that shell". The 

 plain olive-green or yellowish form is fenestrata; with broad ir- 

 regular longitudinal stripes, fiihnmans ; with narrow irregular 

 stripes and bands sepulturalis ; with a light pearl-gray ground 

 color and less conspicuous markings the more pronounced var. 

 madeaya.
