<collectionCode id="0CE79B6BEF06CCAAAD9C68FC012308EF">AT</collectionCode>

<collectingCountry id="29669ACC1A401063AA2B4C49103DC679" name="American Samoa">AS</collectingCountry>

<collectionCode id="2038C63E608D153A2D477F866B1CC8B5">AT</collectionCode>

), located at the valve face / mantle junction, extending more onto the valve mantle, isolated from neighbouring striae. Pore fields composed of usually 2–3 rows of small, rimmed pores (Fig. 2 AU). Girdle composed of several open, plain copulae (Fig. 2
|
||
<collectionCode id="A62AD5C30A2A8A69F00776D45DE36549">AQ</collectionCode>
