Remarks. Maddocks (1969) described B. mozambiquensis from the Mozambique Channel, the Southwestern Pacific and the Gulf of Mexico (1140 to 3850m). The specimens studied herein: (1) are more smoothly rounded larger than the ones described by Maddocks, which present angulated lateral outline; (2) present a more acute posterior margin.
