tained 3.3-3.$ in total length of body in R. heckscheri, while 2.7-3.1 

 in total length in the other two species; 4th finger shorter, contained 

 8.0-8.6 in the total length, while 5.6-7.1 in total length in the other 

 two species; internasal space less than the upper eyelid width in this 

 species while greater or equal in the other two; males with tympanum 

 much larger than eye; thumb enlarged, and throat darker and with 

 yellow; back more warty, in male. 



Voice: One call is a snore or snort, and another a peculiar, snarl- 

 ing, explosive grunt. 



Breeding: They breed from April to mid-July. The eggs are 

 probably a surface film. The tadpole grows large, 3 7/8 inches (97 

 mm.). The young tadpole is black with a gold band across the body 

 and the tail clear. The mature tadpole is dark in body with black- 

 rimmed tail crests. The tooth ridges are 2/3 or 3/3. The tadpole period 

 is probably 2 years. It transforms in June at 1 1/5— 1 9/16 inches 

 (30-39 mm.), sometimes at 2 inches (49 mm.). 



Notes: In August 1922, with a light we captured eight or ten 

 frogs of various sizes from one year frogs to full size adults. We 

 found them in the shrubbery and on the banks about the bases of 

 trees. 



June 9, 1928., Callahan, Fla. Later we went over to Mr. Davis' 

 brick yard pools and found many transforming frogs here and count- 

 less tadpoles. Sometimes these tadpoles were so thick, one could 

 reach in with the hand and catch them. On the east side we saw an 

 immense school of little black ones with the yellowish crossbands. 

 Amongst them are some bigger ones about 1/2 inch in body. This 

 means at least two lots have already bred. . . . These pools are with 

 water lilies, arrow-head, water hyacinth and many other plants. 



June 8, 1928. Callahan, Fla. This afternoon we went to the type 

 locality for Rana heckscheri and saw lots of tadpoles amongst the 

 vegetation. We captured about 12 transformed ones. One can ap- 

 proach them when their heads are out of water. Some rest on the mud 

 of the bank. Many tadpoles here have four legs and a long tail. 

 We went along in the pickerel weed on the east side of bridge where 

 it is shady, 5 p. m., and finally saw a large one. We slowly approached 

 from water side with a net and came close enough to catch frog. We 

 started skirting several edges and soon saw another on the bank 

 amongst pickerel weed. By crawling upon it we caught it, and it 

 squealed. The children went along and frightened another which 

 gave a startled note of the R. catesbeiana order. These two are the 

 largest we have caught. They are bigger than any greenfrog. The 

 transformed ones are somewhat like greenfrogs but with more in- 

 tensified spotting on the belly. These transformed ones and the adults 

 have no costal folds.
