Original Description: From Dall, 1890 (p. 34):“Rare in the Caloosahatchie beds. Shell elongated, acute, sharply sculptured, with a very small, smooth nucleus; spiral sculpture on the later whorls of (between the sutures three, on the last whorl eight or nine) rather fine, elevated, clean-cut even threads, not enlarged where they pass over the ribs; there are also a few close threads on the canal and one in front of the suture, beside a uniform, extremely fine spiral striation, only visible with a lens, which covers the whole shell; transverse sculpture of (on the last whorl ten) rounded ribs, strongest just in front of the fasciole, where they shoulder the whorl and extend forward to the canal; fasciole rather wide, well excavated and somewhat undulated by the ribs; terminal varix not very marked; notch deep, rather wide ; aperture moderate, with a well-marked callus on the pillar; canal short, rather strongly recurved, which, with a sort of constriction behind the canal, gives the siphonal fasciole great prominence, while there is a shallow chink behind the callus of the pillar, Max. lon. of shell 14.0; max. lat. 5.3 mm.

This is an elegantly sculptured little species, not very close to any of the preceding.”
