Description
The size of the shell varies between 25 mm and 85 mm. "The shell is long and oval. The spire is very near the margin. The surface of the shell is spirally lirate; the lines are unequal, rounded and crossed by low folds indicating former positions of the peristome. Its color pattern is reddish-brown, scarlet and green in irregular patches and streaks. The coloration is very variable. The oval perforations number usually 7 to 9. There is no angle at the row of perforations, and the space between perforations and the columellar margin has unequal spiral cords, not coarser than those of the rest of the disk. The inner surface is silvery with light green and red reflections. The two sides are equally curved, and the back is quite convex. The columellar plate is rather narrow, flattened, sloping inward, not in the least truncate at the base. It is so wide above as to wholly conceal the cavity of the spire.
This species is variable and rather bright in coloration, distinguished by its long oval form, numerous perforations and spiral liration."
Distribution
This species occurs in temperate northwestern Pacific Ocean off Japan, Taiwan, Vietnam Bạch Long Vĩ, Cô Tô, Hạ Long Bay; off Australia (Northern Territory, Queensland, Western Australia), and in Indonesian waters (Bali) and off New Caledonia. The shell from these last two sites differ somewhat from the holotype by being a bit more elongate and having a dark sepia color.
