Note 9 — On the Moulting of the common Lobster (Homarus vulgaris) and Shore Crab (Carcinus mænas). By S. James A. Salter, M.B., F.L.S., F.G.S.
Reading edition
The suspicion above expressed has been fully confirmed by observations made by Mr. J. J. Bennett, the Secretary of the Linnean Society. Mr. Bennett informs me that, in an aquarium in his possession, an Astacus fluviatilis has twice cast its shell, and the process of moulting was on each occasion accomplished without any splitting of the shell at the joints of the claws.
