Diagnosis
ReferenceDiagnosis
A. Rosenkrantz 1970Large-sized aporrhaid with high evenly tapering spire and protoconch as in Anchura. Sculpture consisting of numerous fine spiral cords of variable strength, one noded spiral zone on the penultimate whorl and three marked keels on the body, the uppermost situated well below the suture, noded and extending out onto the expanded outer lip. Collabral axial ribs on all whorls, strongest on the penultimate whorl producing nodes by intersecting the median spiral zone here and the uppermost keel on the body. Rostrum rather long but somewhat shorter than in Anchura s. str. This aporrhaid, like Anchura and Drepanochilus, is provided with only one lateral digitation corresponding to the upper, noded keel of the body. The two lower smooth keels attach an outer smooth lip. The wing is very oblique forming a rather large angle (about 68°) with the axis. Posterior edge of the wing as in Anchura and Drepanochilus with a very deep furrow on the inner side. Anterior edge forming a thick, prominent, blunt lobe somewhat similar to the lobe in Perissoptera.
