Proximal brachials smooth, cylindrical, and not in lateral contact. Single known specimen has 14 arms; synarthry between primibrachials 1 and 2; secundibrachials with an axil at second or fourth ossicle or undivided; placement of syzygies depends on whether the secundibrachial series is part of the undivided arm (syzygy between secundibrachials 3 and 4) or terminates in an axil and ray division (no syzygy between secundibrachials 3 and 4).
