The key is a guide to the identification of the 28 British species of the Lower Carboniferous coral family Lithostrotionidae. Each species is illustrated diagrammatically, emphasizing those features which distinguish it from comparable forms. The stratigraphical ranges of these species through the Lower Carboniferous are shown in tabular form.
Fifty-tree species of tetracorals from Eichwald's collection have here been revised, described and illustrated. Stratigraphic range: Ordovician through Lower Permian. Most names given by Eichwald have lost their priority (nomen oblitum), but the present writers ,suggest to keep them for the species which were not described after Eichwald's publication.
