Pustules generally ordered in rows between impressions of external costellae but also in concentric rows spaced at the same distance as the radial rows. Brachiophores delicate, diverging at about 100–110˚. Muscle field generally not impressed, otherwise reaching about 25% of valve length. Median ridge absent, but pustules becoming slightly larger and occasionally developing into two or three weak, radial rows of tubercles in larger specimens. Low peripheral rim occasionally present in larger specimens.</paragraph>
