|---|---|---|
| J.B. Trask 1855 | Shell thin: discoidal, and orbicular; three and one-half convolutions, each smaller one of which is unconcealed by the larger; convolutions nearly round: slightly undulating well-defined costs on each whorl, which appear uninterrupted, and on the last convolution are about one-tenth of an inch asunder; the ribs become more approximate toward the ventral portion of the whorl: between the larger ribs are seen smaller divergent rudimentary costae which appear to converge about midway from the dorsum to the sides of the last whorl: siphon ventral ; dorsum round; septa arborescent; umbilicus perforate; greatest diameter four and three tenth- inches. Aperture one and two tenths inches. |
