5<3 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 origi- 

 nally 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.
