Shell of Julia sp. 1

Here are detailed shell photos of Julia sp. 1 from Hawaii to accompany my earlier message.
On Maui, shells of Julia sp. 1 are common in sand samples that include material from moderately exposed to exposed rocky habitats. All told, I've seen several thousand valves with a maximum shell length of 1.9 mm. The color is highly consistent with the shell marked only with broad, radiating bands of lighter and darker green. In contrast to the other three species, the posterior margin of the shell is broadly rounded. The hinge is moderately large with a central knob that is arcuate and lacks a prominent terminal depression. There are a series of fine, ratchet-like ridges on its inner surface.
I've found shells in sand samples (sent to me Pauline Fiene-Severns and Jerry Flora) from Indonesia, Midway Atoll, Raratonga and Magaia(Cook Islands).
The shell photos are of a closely matched (though lightly worn) pair 1.6 mm in length. They were in sand samples collected from beach drift at Maalaea Bay, Maui in 1986 and 1987.
