Nine euthecosomatous gastropod taxa erected by M.L. Tembrock (1989) are revised, seven of which are either unrecognisable or junior synonyms of other species. Two taxa, Spiratella flandrica and S. lotschi, are accepted as valid. New illustrations of the type specimens, whenever available, are presented.
