from West White Beach, Christmas Island. All specimens show the cardinal process of the dorsal valve with prominent median keel, large diductor scars with elevated median ridge, and massive calcitic deposits, (“bouffant-like” in 3K) in anterior part of brachial lobes. See text for dimensions. All specimens in MfN, Berlin.
