This memoir is the result of over thirty-nine years' work among the crinoids of the Scottish Carboniferous limestones. When I began the systematic collection of these fossils few records were noted in any publications dealing with Scottish geology, and in our national museums such as those of Edinburgh and Glasgow there were, and still are, comparatively few species represented. In the official memoirs of the Scottish Geological Survey, dealing with typical Carboniferous counties like Fife and the Lothians, little more than a dozen species are recorded. Some, if not most, of these records are of doubtful value.
