Mytilicola intestinalis is a worm-like copepod first found in 1902 by Steuer1 in the intestine of the mussel Mytilus galloprovincialis from the Gulf of Trieste; since then, there have been a number of other records both from this mussel and M. edulis2. All these were from the Mediterranean area; but in 1939, Caspers3 found it in mussels from the Bremerhaven–Cuxhaven area of the German North Sea coast, and, in February 1946, I found that mussels from the mouth of the River Blyth, Northumberland, were parasitized. More than 90 per cent of the Blyth mussels examined were found to be infected; in one case, 18 specimens were obtained from a single host.
