IntroductionDuring the last fortnight in September of 1965, 1966 and 1967 littoral species of Spirorbis were collected by the author and, during the early part of April 1966, sublittoral species were collected by the British Museum (Natural History) and University of London Sub-Aqua Expedition. Ten species, including one new to the British Isles and two new to science, were found to be present. Details of their occurrence, together with the descriptions of the new species, are contained in this report. Representative series of the material collected are deposited in the British Museum (Natural History).
