 simply to facilitate the exchanges between tlie United States National 

 Museum and uuiseums iu Europe, no attempt has been made to distrib-

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

 retained. 



One species {Gasferosfeus Blancliardi, Sauvage), which was described 

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

 Gasierosteus imngiiius^ Linn. ( := Fygostciis occidcnfaliSj (C & V.) Breevort),
