Description

As Cominella alfredensis Bartsch, 1915
Shell fusiform, flesh-colored, variously mottled and clashed with brown. Nuclear whorls decoUated. Post-nuclear whorls having a sloping shoulder which extends over the posterior three-fifths of the whorls between the sutures, marked by weak axial ribs, which are best developed at the anterior edge of the shoulder and extend but feebly across it; anteriorly the ribs become much enfeebled, 13 ribs occur upon the last and 14 upon the preceding turn. The spiral sculpture consists of 10 irregularly developed, low, broad cords, of which the three on the shoulder are almost obsolete and scarcely discernible; while the four upon the base are fairly strong. In addition to these cords the entire surface is marked hy fine more or less regularly developed, punctate, spiral striations. Posterior angle of aperture acute, outer lip provided with nine slender denticles a little within its inner margin; columella glazed with a moderately strong callus; parietal lamellae only slightly developed.
The type and two specimens, Cat. No. 187019, U.S.N.M., were collected at Port Alfred (Coll. No. 554). The type has lost the early whorls; the last four remaining measure: Length, 29.2 mm.; diameter, 15 mm.
