A new species of multi-tentacled box jellyfish from eastern Arnhem Land along the Gulf of Carpentaria, renowned locally for occurring only in the so-called ‘safe season’ (i.e., the dry season), is described. Chiropsella bart n. sp., differs from other chiropsalmids in maturing at a much smaller size, in its mature tentacle number, in having coalesced gastric saccules in the form of a kidney-bean-shaped knob, and in having very long pedalia with the branches and tentacles clustered near the distal end
