Diagnosis
ReferenceDiagnosis
W. P. Popenoe 1937These internal features of the shell have been determined for Legumen ooides-cardinal teeth, three in each valve; lateral teeth absent; right anterior and median cardinals short, slender, prominent, subparallel, situated almost directly beneath the beaks; right posterior cardinal long, moderately prominent, subparallel to the nymph, bifid, the anterior element of the tooth being short and splintlike; left anterior and median cardinals also short, slender, and prominent, diverging from one another ventrally at an angle of approximately sixty degrees; left posterior cardinal long and thin, joined to the ventral border of the nymph; hinge-plate shallowly excavated immediately in front of the anterior cardinal teeth; lunule undefined; ligament submarginal, about one-half the length of the posterior dorsal margin of the shell; pallial sinus rather short, broad, blunt, directed toward the anterior adductor scar.
