Stromboidea
Original Description of Harpago tippanus by Conrad, 1858, p. 331:
- "A fragment, with smooth subangulated volutions, a carinated line revolving at the base of each; rostrum of the labrum profoundly extended, trilobate, the central and upper lobe profoundly carinated in the middle; substance of the shell thin. The labrum has evidently been extended above the apex, but only a slight trace of it remains near the upper part of the spire. The specimen is evidently a young or immature shell."
