As Plicifusus griseus, Dall,1877
Shell thin, solid, rather acutely pointed when perfect, but almost in-variably eroded at the tip, eight-whorled, covered with an olive-gray epidermis, the substratum, pillar throat, and reflected lip milk-white; nucleus eroded, small; suture distinct, not appressed or channeled; whorls full and rounded; transverse sculpture of twenty to twenty-five, narrow, somewhat irregular, arcuated, wave-like ribs, which on the earlier whorls often reach from suture to suture but are strongest on the periphery; some specimens have them faint, others, the majority have them strong, but in all they become more or less obsolete on the last whorl; spiral sculpture of rather coarse, rounded, not much elevated cinguli, with narrow interspaces, slightly reticulated by the incremental lines; variable in strength but usually covering the whole surface; in five young specimens the surface over the sculpture is somewhat polished; in adults it has a more rude appearance; aperture oval, wide; the outer lip flexuous as in Buccinum, more or less (in some specimens, very much) reflected; margin simple, smooth; body polished, the surface slightly excavated and glazed; pillar thin, simple, twisted; the axis widely pervious in the young, minutely or not at all in the adult; canal short, wide, slightly recurved; there is no siphonal fasciole; operculum large, thin ovoid, slightly curved, with an apical nucleus. Max. long, of shell, 32; of altitude, 18 mm. (Dall.)
