362 Frogs of the Okefinokee Swamp 



fringe is a very short row (sometimes absent) which is from 2/1 5-1 /16 the 

 upper fringe. The ends of the lateral row not extending beyond end of upper 

 fringe. Median space between lateral rows six to eleven times the length of 

 either row. The first lower labial row slightly longer or equal to horny beaks 

 in length, and sometimes divided in the middle. The second row almost 

 equal to first. The third row quite short not nearly as long as in R. catesheiana 

 usually almost 1/2 of the first row not 3/4 or 4/5 as in R. catesbeiana, or 2/3 as 

 in R. grylio. It is contained one and one-half times in the horny beak and as 

 much shorter than the single row of lower papillae. On the side of the labium 

 the inner papillae (inside outer row) extend mesially beyond and beneath the 

 second lower labial row of teeth, but not to third row (more like R. grylio).

The dimensions of the largest tadpole are : 



General remarks. On July 9, 1922, at Thompson's Landing, St. Mary's 

 River we found in a pond sotne tadpoles almost white in appearance yet they 

 were not albinos. They were in a little pool with chalky white water and were 

 colored accordingly. 



LARVAL PERIOD 



Normally I believe this species spends one winter as a tadpole. In 192 1 

 it was difficult to find tadpoles inside the swamp after May 15. In 1922 we 

 found more in shaded ponds on the outside east of the swamp. On July 15 

 in one sphagneous pool where the species was laying we found a few tadpoles 

 nearing transformation. On August 11 at Camp Pinckney we found quite a 

 number of large tadpoles in five deeply shaded pools. But even on the outside
