THE HABITAT OF THE EURYPTERIDA
SYNONYMY
In order to facilitate the use of the preceding tables, I shall give here a synonymy which is not complete, but is intended only for the convenience of anyone looking for a species which has been revised, and which would not appear under the genus to which it was originally ascribed. Such a synonymy is particularly necessary for species described in foreign literature. Most of the revisions have been made by Clarke and Ruedemann for American and some European species, by H. Woodward for species in Great Britain, by Semper for those in Bohemia originally described by Barrande, and by numerous other writers who have revised only single species.
