Shell moderately inflated, strongly elongate transversely, elliptical-ovate in
outline.Umbonesmarkedly anterior, approximately situated at the anterior 1/3 of shell length.Anterodorsal
and posterodorsal margins straightish and gently sloping. Ventral margin broadly rounded. Lunule
lanceolate, delicately outlined by a finely impressed line. Outer surface smooth and glossy, only with
shallow concentric growth marks, but devoid of undulating oblique grooves on medial part of the shell.
Hinge narrow, concentrated under the umbo of each valve, with 3 radiating cardinal teeth but without
lateral teeth. Pallial sinus deep, markedly ascending, rounded in front and approximately extending
over the posterior 2/5 of shell length. Internal margins smooth. Colour: outside of shell highly glossy,
cream to pinkish brown, with a netted pattern of darker tan to greyish brown zigzag lines. Dorsal margins
with distant, dark purplish brown, short and transverse lines anterior and posterior to the umbones. Interior
