Auckland to Duuedin (Hution) ; Port Denison, Queensland(Co/ipim/er).The specimens from Port Denison, which may belong to thisspecies, are very like T. norveyicus and T. palmulata externally.Thesculpture is similar, but the notch or angle in the anterior side isnot quite so deep as in the former.

The pallets,wanting in the specimens before me, are said to be " elongate,slightly curved, penniform."Mya arctica, Linn.2. Saxicava arctica.Hah.
