pearance; more pointed head and narrower snout than in R. cates- 

 beiana, and with all the hind toes except the fourth proportionally 

 longer; webs to the tips of toes. 



Voice: The call is a grunt like that of pig or an alligator. It is 

 rough and guttural. 



Breeding: They breed from May I through September, generally 

 in humid weather, with night temperatures of 65-70 degrees and day 

 temperatures of 85-90 degrees. The crest is in June and July. The 

 black and white eggs are in a surface film 12x12 inches to 12 x 25 

 inches, and attached to vegetation. The egg is 1/16 inch (1.6 mm.), 

 the outer envelope 1/6-1/4 inch (4-6 mm.), merging into the jelly 

 mass. The greenish tadpole is quite large, 4 inches (100 mm.) with 

 tail long, sharply acuminate. The tooth ridges are 2/3. After a tad- 

 pole period of 1 to 2 years, they transform from April 24 to July 19, 

 at 1 1/4-2 inches (32-49 mm.). A young transformed R. grylio looks 

 much like an adult or half grown Carpenter frog, (R. virgatipes). 



Notes: On April 25, 1921, (Billy's Island) we went with flash- 

 lights after Rana grylio. On the vegetative carpet and lily pads were 

 untold numbers of Acris, on the lily pads and on the bushes, Hyla 

 cinerea, and amongst the pickerel weeds, different sizes of Rana 

 grylio. In all, thr,ee of us secured only 6 adults and one transformed 

 specimen. Later I found that they could be picked up rather easily 

 with a flashlight. 



On May 6, Dave Lee went out on Billy's Lake at night with, a 

 torch to catch small fish for bait. With a small dip net he would scoop 

 in front of a Rana grylio, and usually catch- it. All in all our main 

 reliance was to wade about at night on the 'prairies' or in open cypress 

 ponds and by means of a flashlight catch them by hand. 



On May 11, we found plenty of R. grylio at night along the edges 

 of Billy's Lake. They usually were at the edge near the bushes or 

 under them amongst brush or in maiden cane. Usually when one tried 

 to photograph them they were too much surrounded with vegetation 

 or sticks.
