474 Frogs of the Okefinokee Swamp 



ing). None of our 52 adults examined could be sexed externally if below 21 

 mm. One therefore seems inclined to extend this 15-17 mm. group to 20 mm., 

 and pronounce 21 mm. onward as of the second year group. 



On June 11 three females were taken 24, 25 and 28 mm., possibly two 

 modes or groups. On May 23, 192 1, we took seven adults one group of four 

 23 mm. cT, 23 mm. 9 , 24 mm. cf , 25 cf , and a group of three 28 mm. cf, 

 29 mm. 9, 30 mm. 9. On June 23, we took four specimens 24 mm. cf, 



27 mm. c^, 28 mm. 9 , 28 mm. cT. On July 4, 192 1, we secured a 24 mm. c? 

 and 28 mm. 9 . On July 3, 1922, a 23 mm. cf , and a 27 mm. 9 . At least 

 36 of the 52 adults mentioned are 26-21 mm. Our evidence seems to be 

 8.5-12 mm. at transformation; 15-20 mm. first year olds; 21-26 or 27 mm. 

 second year olds; 26 or 27-30 mm. our largest adults. 



Examination of some of the U. S. National Museum material (59 frogs) 

 shows transformed individuals at 11-12 mm. One set of five specimens 

 (U.S.N.M. 9954, 38781-82 F.B. Meek) from Little Sarasota Bay, Florida, 

 are 17.5, 18, 18.5, 18.5 and 18.5 mm. respectively. One group from Calcasieu, 

 La., G. Wiirdemann (U.S.N.M. 3978) gave 17, 17, 17.5, 19, 21, 22, 23 mm. 

 cf, specimens — two groups (17-19, 21-23). One other group (U.S.N.M. 

 25420-21) of two specimens, 18.5 mm. and 22 mm. cf represent a sexless 

 stage and a sexual stage externally. Thus far the above material shows 

 transformation at 11-12 mm.; a group 17-19 mm.; and a group of 21 or 22 

 mm. onward, a sexually mature assemblage. 



On April 18, 1897, at Wilmington, N. C, Dr. Paul Bartsch collected 5 

 specimens, (U.S.N.M. 37060-64) three of which were 20 mm. 9 , 20.5 mm. 

 cf and 20 mm. cf, and two of which were 26 mm. cf and 27 mm. <f. Have 

 we two model groups? Or on May 23, 19 10, Julius Hurter, Mobile Co., 

 Ala., takes two (U.S.N.M. 42548-49) 25 mm. cf and 28 mm. d^. Two days 

 and five days Later he collects a 28 mm. cT (U.S.N.M. 57698) and another 



28 mm. cf (U.S.N.M. 57697). Or May 1 5 at New Orleans, La., they (U.S.N.M. 

 53188-87) have a 20-5 mm. cf and 27 mm. 9 . 



Or on May 25, 1891, J. Hurter takes in Missouri two females (U.S.N.M. 

 57700-01) 21.5 mm. and 31 mm. respectively. These selected instances show 

 11-12 mm. at transformation, 17-19 mm. an intermediate group, a 20-25 mni. 

 group and a 26-31 mm. group. A plotting of the whole 59 frogs reveal 11-12 

 mm. at transformation, 17-19 mm. apparently first year olds, 20-25 mm. 

 second year olds, 26-31 mm. three year olds. We have no Okefinokee speci- 

 means at 20 mm. The U. S. National Museum material shows sex externally 

 at that size (U.S.N.M. Nos. 37062-64, 53188) and our specimens at 21 mm. 

 Our largest Okefinokee specimen is 30 mm., a female, but the U. S. National 

 Museum collection has several females from 32 (U.S.N.M. 57702, 37o7)-36 

 mm. (U.S.N.M. 57614, 57703-4). We have in our collection four specimens 

 from Raleigh, N. C, August 1893, namely, 26 mm. cT, 26 mm. 9, 27 mm. 

 cf and 32 mm. 9 . Is the last of a different mode? Are all these 32-32 mm. 

 females more than three year olds? The whole evidence seems to be 8.5-12 

 mm. at transformation, 15-19-20 mm. for first year olds, 20 or 21 mm.-25 or
