These show a sufficient resemblance to warrant our referring Diplostylus provisionally to the Amphipod order. I am very much obliged to Mr Bate for this analogy (which would certainly have escaped me in Milne-Edwards's work). Mr Bate's late papers on the Amphipods (Ann, Nat. Hist., 1861) admirably illustrate this peculiar group. " EuRYPTERUS, a large species allied to E. Scouleri, Hibbert (Fig. 50). " A mere fragment of a large body-ring, which nevertheless indi- cates a species nearly as large as the great Scotch Eurypterus [E. Scouleri, Hibbert). "The large ' teardrop-tubercles' along the hinder margin suffi- ciently show the nature of the ornament. These, in all probability, were replaced by spines on the carapace, as in the British Coal measure species. " The carbonaceous film which remains in part on the surface, cracked (by shrinking) into minute areola, represents evidently a corneous substance, from which the animal matter has been dissolved away. The suggestion of Professor Huxley, that the large Euryp- teridcB had a thick crust like that of Limulus, with but little calcareous matter, is most probably tme. " Locality—Coal measures, Port Hood, Cape Breton. Fig. 50.—Fragment of Eurypterus. Fig. 51.— Tail of Euryptenis (?).. " Eurypterus (?), tail of.
