Remarks
Original combination: Bittium podagrinum Dall, 1892.
Original description: From Dall (1892, p. 274): “Pliocene of the Caloosahatchie and Shell Creek, Florida, Dall and Willcox. Shell small, swollen, with three small, inflated, smooth and polished nuclear and four rapidly increasing subsequent, reticulated whorls, the last third of the last of which is contracted so as to be smaller than the antecedent coil of the shell; spiral sculpture of, on the body-whorl, about four obscure grooves, separating wider, somewhat rounded, flattish interspaces, and cutting more or less distinctly the numerous flattened, straight riblets which cross from suture to suture, sometimes nodulated at the intersections, but more commonly flattened ; upper whorls of the spire flattened, the penultimate whorl swollen, the last whorl contracted in its later half, which is destitute of riblets and shows an obscure varix; base spirally sulcate or sometimes nearly smooth ; aperture ovate, oblique, the inner lip raised and nearly continuous with the peristome; canal practically obsolete; pillar not distinct from the raised labrum ; outer lip thin, simple; throat non-lirate ; suture very distinct. Lon. of shell 4.75 ; max. lat. 2.75 mm. This curious little species varies in obesity, but always has a swollen look. It would probably be referable to Aneurychilus, if that be regarded as a section of Bittium.”
Holotype: USNM 113333, “Pliocene. Caloosahatchie River, near Fort Thompson, Florida” (Schuchert et al., 1905, p. 102).
