1% inches in length, similar to latilirata, but not so heavy, with 10 to 12<br />

smaller, concentric ribs which are thin at their ends. From a side view, the<br />

I inch in length, very thick and solid, with 5 to 7 large, bulbous, concentric<br />

ribs, usually rounded, but may also be sharply shelved on top. The<br />

ribs are not thin and flattened at their ends. Lunule heart-shaped, and, from<br />

a side view, its dorsal margin is almost straight. Surface of shell glossy, cream<br />

with rose and brown mottlings. Rather uncommon offshore in about 20<br />

purple or brown. Brackish water specimens are dwarfed. A common sandy<br />

shore species.<br />

A. brasiliana Gmelin (West Indian Pointed Venus) which is twice as<br />
