The name Rhine, which is apparently of Celtic origin, is of uncertain etymology, the most favoured derivations being either from der Rinnende (the flowing), or from Rein (the clear), the latter being now the more generally accepted.
Milne Edwards has identified ten species which occur in Australian seas also, and Rein mentions, as belonging to the same category, the helmet-crab or horse-shoe crab (kabuto-gani, Limulus longispina I-Ioeven).
