INTRODUCTION^ 



A large number of investigators have from time to time con- 

 tributed to our knowledge of the parasites of turtles. Among 

 these contributions the classical work of Looss, Ueber neue itnd 

 hekannte Treinatoden aus Seeschild-Kroten, stands out pre- 

 eminently and will for a long time to come be the model to which 

 other investigators will conform and which will stimulate the 

 investigations in parasitology in all countries. 



* It is fitting that I should state that Mr. Covey is entitled to the credit for 

 having done the major part of the w^ork in this investigation. The work 

 was done under my direction and I have carefully gone over all of the data 

 and have studied the material used in this investigation and can vouch for 

 its accuracy. F. D. B.
