The above description is amplified by the following note :—
"Remarkable for the smoothness of the beautiful green
epidermis, which is very thin, and, when rubbed off, exhibits a
plain white colour, not nacreous, underneath. The anterior
cicatrices are confluent, the posterior nearly distinct, the apical
• ones situated under the cardinal teeth. Cavity of beaks very
deep ; a few ruga? cross the strise on the posterior slope. In
general characters it approaches most nearly to the Jellingyhy
variety {delta) of U. [P. (P.)] favidens, which has a more tumid
Ovate form, a regular, suleate, olivaceous surface, longer and distinctly
angulate-flexuous umbonal furrows, and a broad lunule." *
