Original Description: From Dall, 1890 (p. 38): “Rare in the Caloosahatchie beds and at Shell Creek, Florida. Shell slender, eight or nine-whorled; nucleus small, smooth, three-whorled; subsequent whorls spirally sculptured with larger and smaller squarish elevated threads, which, on the last whorl, tend to be alternately strongand weak; the two series are remarkably uniform among themselves, except that on the periphery two or three of the primary threads will be a little more prominent than the rest, while on the fasciolar region there are five or six uniform large secondary threads, close-set, without any primaries; the transverse sculpture comprises on the earlier whorls eight or ten rounded riblets well defined near the nucleus, but becoming less distinct and finally obsolete on the later whorls; the last whorl and a half has no trace of them; whorls rounded, suture distinct, but not channelled or appressed; incremental lines distinct, slightly elevated, neatly reticulating the secondaries and beading the primaries; aperture elongate, rather narrow, not differentiable from the canal; outer lip smooth within, inner lip with but little callus; notch wide, not very deep, canal hardly indicated. Max. lon. of shell 15.5; max. lat. 6.5 mm. This elegant species is nearest the recent D. limnaiformis Kiener, from which it differs in its stronger sculpture, proportionally longer spire, less reticulated early whorls; fuller and more accentuated whorls, deeper notch and less arcuate columella.”
