110 PROCEEDINGS OF THE ACADEMY OF [Mar., 



The bulk of the material described in the present paper was 

 obtained by the expedition from Cornell University during the 

 summer of 1912, at which time the swamp was entered from the 

 southwestern side and a permanent camp established on Billy's 

 Island, located in the centre of the swamp. From this camp 

 side trips were made from time to time throughout the summer, 

 and a fairly accurate idea of the geography and biology of the region 

 was obtained. 



Most valuable services were rendered to this party by the Lee 

 family, living on Billy's Island, the only human inhabitants of the 

 interior of the swamp, and practically out of touch with the outside 

 world. Their primitive mode of living had adapted them to a 

 marvellous degree to the appreciation of the wild life about them, 

 and their observations and knowledge of natural phenomena proved 

 to be surprisingly accurate. The older men and boys were indis- 

 pensable as guides while the party was in the swamp, and on the 

 exit of the party a container was left with them to be filled with 

 specimens which might come to their hands later in the year. This 

 container, full of material chosen with evident care and good judg- 

 ment, was received November 15, 1912, and the specimens thus 

 secured proved a valuable addition to those previously collected. 

 In December, 1913, data were obtained on the winter condition of 

 some of the forms here noted. 



The list of species here described is of course hardly more than 

 a check-list of those reptiles noted during the two months which 

 the party spent in the Okefinokee, and is no doubt very incomplete 

 as regards the extent of the reptilian fauna of the swamp, but it is 

 hoped that it will serve as a basis for future work and as an aid to 

 systematic zoologists interested in the forms of the region under 

 discussion. 



Acknowledgments are due to Dr. Leonard Stejneger, of the 

 United States National Museum, for the privilege of examining 

 types in the Museum collection, and to Mr. R. W. Bennett and Mr. 

 Cornelius, of Fargo, Ga., without whose courteous assistance it 

 would have been impossible to have transported our material out 

 of the swamp. 



The nomenclature and synonymy here adopted is that of Arthur 

 E. Brown in Generic Types of Nearctic Reptilia and Amphibia/"
