had a stump of a tail and a triangle between the eyes. It is Acris transforming 

 and transformed. These Acris are about the size of an adult Pseudacris 

 ocularis. Strangely enough we took a pair the female of which laid when 

 these tadpoles were transforming. Transformation period must, therefore, 

 be a long extended one. On June 14 we took transformed frogs at Minne 

 Lake. On June 16 on Billy's Island in another cypress pond we found all 

 stages to transformation. On the 17th more transformed individuals were 

 taken. On July 3 we found many transforming on Honey Island Prairie. 

 On July 12 more were taken on Billy's Island. On July 23 and July 27 

 others were recorded. 



In 1922 we have several transformation notes: "On June 22 found tad- 

 poles with large hind legs." On July 2 "on Grand Prairie and whole area 

 from Lake Seagrove to Grand Prairie are Acris abundant. Found the 

 species transforming, several on lily pads out from the edge of the islets 

 ('houses, camp houses')." "July 13 at Starling Branch crossing we took in 

 overflow crossing a quantity of tadpoles approaching transformation. A few 

 had a black tip to the tail." At the same place "July 24 very few Acris 

 tadpoles. One with 4 legs, long tail, the stage desired." In another pond 

 "July 28 found plenty of transformed Acris and a few black tipped tadpoles." 

 Of another place the same day we wrote "Still a few black tipped tadpoles in 

 pond near the 2nd dreen." 



In August we have a few notes: On Aug. 3-5 on Billy's Island in three dif- 

 ferent ponds they were transforming. On Aug. 17 at the edge of Starling 

 Branch crossing "we found a transformed Acris on the ground." On Aug. 31 

 at two ponds "found several tadpoles with only two legs." 



Our field notes above give in 192 1 dates of transformation from June 3- 

 July 27. In 1922 we have evidences of transformation from June 22 to Aug. 

 21 and F. Harper later, Aug. 29, found the houses (islands on prairies) "cov- 

 ered with transformed Acris. '^ 



In 19 1 2 we secured very little on transformation in Acris gryllus of Oke- 

 finokee Swamp. Then we rite : 



"In some overflow pools on Mixon's Hammock, June 16, 1912, we took 

 several stages of this form. The pools were about a rod from the west end of 

 Billy's Lake and had in it also toad and spring frog tadpoles, killifishes and 

 pigmy sunfishes. Two of the series are at transformation and measure 12 mm. 

 On May 31- June 2, 191 2, on Honey Island Prairie where water is 4-5 feet 

 deep we found them common at the surface either fully transformed or with 

 tails yet visible. These measured 13 mm. These little creatures were resting 

 on the lily pads of the open prairie or on the vegetation around the little 

 islands. It is an interesting fact that in these transformed individuals (even 

 in forms, just before the outpushing of the fore-limbs) the only adult marks 

 are the conspicuous posterior femoral stripes and rarely the interorbital 

 triangle. Several other individuals taken at the same time as the trans- 

 formed individuals measured 16.75-19 mm., and another specimen taken 

 on Floyd's Island June 25 measured 18 mm. The only mark these eight have 

 in common is the same femoral coloration. A series of tadpoles taken June 16
