Remarks

Synonymy: Drillia edilia Dall, 1890: p. 35, pl. 3, fig. 9.

Type Specimen: USNM 97326 (holotype), “Caloosahatchie River, near Fort Thompson, Florida” (Merrill, 1905, p. 235).

Original Description: From Dall, 1890 (p. 35):“Caloosahatchie beds, one specimen. Shell very small, short, with five or six slightly shouldered whorls; nucleus of the same general character as in D. sedilia, but transversely ribbed all over and more elevated ; later whorls with rather faint, close-set, flattened spirals, which override the transverse sculpture but are very faint upon it; the interspaces appear like grooves and are more conspicuous than the spirals; the transverse sculpture of numerous (on the last whorl eighteen) narrow, rather feeble riblets, strongest near the fasciole, which is smooth, excavated and a little scalar ; terminal varix swollen, notch wide and deep; aperture narrow, not differentiated from the short canal. Max. lon. of shell 4.0; max. lat. 1.6 mm.

Notwithstanding the small size and large nucleus of this little shell, it has evidently begun its varix, though the callus on the body is not yet complete. I cannot so far find any other to unite it with.”
