The present notes contain the substance of a paper read 

 by me at a sectional meeting of the Third International Congress 

 of Zoologists held in Leyden (1895), together with descrip- 

 tions of a few additional species. Some of these results have 

 been communicated to my friend Dr. G. Saint-Remy of Nancy 

 and incorporated by him in his recently published " Comple- 

 ment du synopsis des Trematodes monogénèses " ['98]. The 

 following gentlemen have materially helped me in various ways, 

 and I wish here to express my best thanks to them : Drs. C. 

 W. Stiles and A. Hassall of Washington, Prof. A. E. Verrill of 

 New Haven, Prof. F. J. Bell of the British Museum, and Dr. 

 G. Saint-Remy of Nancy. I must also note my deep obligation 

 to Prof. A. Agassiz for enabling me to study in his laboratory 

 in Newport, R. L, where many of the new species described 

 in the following pages were collected. To the authorities of 

 Harvard University and of the U. S. Fish Commission Laboratory
