392 Frogs of the Okefinokee Swamp 



1.4-2.4, average 1.8. Depth (13-20 mm.) of body .9-1.6 in its own width, 

 average 1.14, rarely greater than body. Depth of body 1.8-2.46 in body 

 width, average 2.08. Depth of tail (14-18 mm.) in length of tail 2.6-4.6, 

 average 3.2. Depth of tail .8-1.3 in body depth, average 1.02. Muscular 

 part (9-1 1 mm.) of tail in its own tail depth 1.45-2.0, average 1.72. Spiracle 

 .86-1.2 nearer vent than snout, average i.o, i.e., about equidistant in general; 

 spiracle to snout (17-22 mm.) and spiracle to vent or base of hind legs (17-23 

 mm.). Spiracle to eye (8-12 mm.) in eye to snout (8-1 1 mm.) .85-1.2, 

 average .99, i.e. eye to snout and spiracle to eye usually equidistant. Nostril 

 to eye (4.0-6.0 mm.) equals the distance from nostril to snout (3.5-6.0) mm. 

 Mouth (3.0-7.0 mm.) usually i. 0-1.5 greater than the internasal space (3.0- 

 6.5 mm.), average 1.2. Mouth contained 1. 1-2.0 (average 1.46) in interorbital 

 distance (5.0-10 mm.). Internasal space contained in interorbital space 1.4- 

 2.0, average 1.75. 



The dimensions of the largest tadpole of the 1922 collection are: 



In 1928 we took one 95 mm., one 96 mm. and one 97 mm. in total length. 



General remarks. On June 16, 19 12, at the Fargo, Ga., heronry amongst a 

 swampy tangle of buttonbush Cephalanthus occidentalis, "hurrah bushes" 

 {Leucothoe raceynosa) and "lather leaf" {Clethra alnifolia) the author found 

 some black tadpoles with yellowish white crossbands and surmised that they 

 were the tadpoles of R. grylio. That was a mistake. 



In 192 1 when I returned from the swamp three tadpoles were referred to 

 me from the U. S. Bureau of Fisheries. They were unlike anything we had 

 seen before. Our reply was solely as to the identity of the material. The 

 correspondent, a doctor from Savannah, Georgia, was concerned to know if 

 albinism was common in tadpoles. Some of them were albinos and some 

 normal. A week or so later, August 7, 192 1, Mr. Francis Harper and Marion 

 Lee found a small tadpole in the St. Mary's River, Baker County, Florida, 

 about 10 miles south of Moniac, Georgia. On August 16, 192 1, at Camp 

 Pinckney (3 miles southeast of Folkston, Ga.) St. Mary's River, they secured 

 three (Nos. 32-34) more larger tadpoles. These and the Savannah tadpoles 

 were at hand when we surmised they might be Gopher Frog {R. aesopus) or 

 Sphagnum Frog {R. virgatipes) tadpoles. They are of neither species. 



In 1922 on July 17 at Thompson landing (south of Folkston) St. Mary's 

 River in a cut off overflow pool we found in the water almost a pure culture of 

 a small black tadpole with a gold and white transverse band like those of June 

 16, 1912.
