About 350 nominal species are mentioned. Since the list is intended 

 simply to facilitate the exchanges between the United States ^National 

 Museum and museums in Europe, no attempt has been made to distrib- 

 ute the names in accordance with the latest knowledge concerning the 

 classification and specific identity of the species in question. The names 

 given to them by those who presented them are, with few exceptions, 

 retained. 



One species {Gasterosteus Blanchardi, Sauvage), which was described 

 from specimens sent to Paris from Boston, United States, is referred to 

 Gasterosteus pungitius, Linn. ( = Pyffosteus occidentalism (C. & V.) Breevoi-t), 

 with which it is identical. 



The numbers at the left are those of the National Museum Catalogue; 

 those at tlie right Avere attached to the fishes when they were received.
