reptiles and amphibians. 



Blanding-s Turtle was the only turtle found in the marsh 

 on the point. Snapping turtles and Margined Turtles (Chry- 

 semys marginata) were found in the canals on the island. 



The American Toad and Pickerin's Tree-frog were fairly 

 numerous away from the water, and in the swamp were the 

 Leopard Frog and Ijullfrog. 



In the lake, swimming around, and occasionally ashore, 

 were found both the common Watersnake (Natrix fasciata 

 sipedon) and the Red-bellied Watersnake (Natrix fasciata 

 erythrogaster). Along the shore and among the cedars were 

 found the Puffing Adder (Ileterodon platyrhinus), the Milk 

 Snake (Osceola doliata triangula) and the Garter Snake 

 (Eutania sirtalis sirtalis). Toward the base of the point was 

 found a Black Snake (Bascanion constrictor). In the heavy 

 deciduous timber, climbing the trees, were found several Pilot 

 Snakes (Coluber obsoletus obsoletus). One was brought to 

 my attention by a troop of about fifty warblers, which had 

 gathered about one in a tree about sixty feet high. One of 

 these was the largest snake we killed, measuring five feet and 

 three inches in length.
