400 Frogs of the Okefinokee Swatnp 



In 19 13 (Copeia October 15, 19 15, pp. 46-48). "On July 7 in peaty lake 

 with a clear sphagnum border we found several R. septentrionalis.'" On July 

 1 6th and 17th we examined the place closely. "All along the north edge of 

 the lake were white water lilies, yellow spatterdocks and water shields. 

 These three made a perfect carpet on the water's surface. On these plants 

 during the day the frogs rested." "In the outlet to Otter Lake (Ten Mile 

 Creek between Lake of Bays and Otter Lake) we found them common, 

 July 24, on muddy bottoms where water lilies were abundant. In the same 

 kind of situation they occurred on Porridge Lake, July 28. Another habitat 

 we discovered August 31 was a beaver lake where Cassandra and all the 

 associated heath-like plants grew. Finally, in Fletcher Lake, September i 

 we found them in the shallow, sandy shores amongst pipeworts (Eriocaulon 

 articulatum).'' "This species cannot be called solely a river species; . . ." 



To the last conclusion I still adhere. In general we have found it most 

 commonly in lakes or ponds or if streams these are usually inlets or outlets 

 of ponds or lakes. On June 13-14, 1923, we found it more or less along the 

 whole Fulton chain of lakes, Adirondack Mts. from White Lake to Seventh 

 Lake. Sometimes a few might be in temporary pools beside the state road 

 where they must have travelled over land to reach these places. All in all, 

 it is distinctly an aquatic species. On June 14, 1923, we found most of our 

 frogs at Hellgate Ponds, Onekio, N Y. Here in driftwood pools below a 

 beaver dam we took several R. damitans, R. catesbeiana and R. septentrionalis. 

 Later took several more mink frogs in muddy pools among granite boulders. 



On July 9, and July 26, 1900, Mrs. E. P. Miller and Gerrit S. Miller Jr., 

 recorded these frogs in Peterboro Lake and Peterboro Mill pond on floating 

 Nymphaea leaves, the same habitat in which Bishop in the Adirondacks and 

 we in Algonquin Park found them. 



FIRST APPEARANCE 



None of our records are in the spring and the earliest record of the year is 

 Garnier's statement "It makes its appearance in April" at Lucknow, Ontario.
