Description:
“Shell long elliptical or slightly obovate, generally solid and inflated, with a faint
posterior ridge; beaks moderate, the sculpture not seen; surface with irregular growth
lines, often more or less sulcate, varying from dirty tawny to black, often faintly rayed
behind; left valve with two granularly roughened pseudocardinals and two curved
laterals; right valve with one pseudocardinal, a feeble lamellar tooth above, and one
lateral with a vestige of another below it in old shells; laterals granular; muscle scars
small, well impressed; nacre white, salmon or flesh-colored, sometimes deep purple,
slightly thicker in front. The male is often nearly rounded or sub-biangular behind, the
posterior end at or above the middle of the height; the female shell is considerably
swollen at the posterior base, and its posterior end is more elevated than that of the male”
(Simpson 1914, p 100-101).
