LEA, I. 1833. Contributions to geology. vi, 227 p., pls. 1-6. Carey, Lea and Blanchard. Philadelphia, 1833 [p. 88]
P. Lyelli* Plate 3. Fig. 67.
«Description. Shell longitudinal, rounded below, angular above, compressed; ears very unequal, having a channel on the larger one; substance of the shell thin; ribs about twenty-two, rounded, slightly imbricate; beaks acutely angular.
Diam...... Length .8, Breadth .7, of an inch. Observations. This species differs from the last described in being more elongated, in having very unequal wings, in having a channel on one wing, and in having no alter nate ribs. A single small valve accompanied this species, which appears to be different, the ears being not quite so unequal; further specimens may prove it to be worthy of a specific distinction. If so, I propose the name of minutus.» * Named after the eminently distinguished geologist Charles Lyell.
ISAAC LEA, 1833
