If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|G. W. Tyron 1884||Shell massive, allied, in general form, to Oliva, spire low. Outer lip simple, not thickened nor crenulate ; inner lip incrusted, callus marked posteriorly, without teeth or folds ; canal slightly recurved ; anterior extremity of the mouth notched, and a small sinus at the posterior extremity of the aperture, where the oiiter lip unites with the body-whorl. Surface ornamented as in some of the Buccinidse. This curious form is probably a link between Buccinum and Volutharpa.|
