Hyla femomlis 289 



beak is contained about 2.0 times in the upper fringe. The median space be- 

 tween the lateral second upper labial very short, 6-10 times the length of 

 either lateral row. The inner papillae extend under the third row of lower 

 labial teeth making at least two rows of papillae across the lower labial border. 

 In the lower labial corner there is a heavy papillary series of 4 or 5 rows like 

 H. versicolor or H. squirella. The lower third labial is long and is usually 

 about 1. 1 0-1.2 in the first or second row, longer than in H. squirella and is 

 larger than the horny beak. The first and second rows are about equal and 

 1. 4-1. 6 greater than the horny beak. This species, like Hyla versicolor and 

 Hyla squirella has a very angulate upper fringe at its middle.

General remarks. In 191 2 we provisionally identified these tadpoles as of 

 Acris gryllus because of similar pattern on the tadpole tail and Acris rear 

 femur coloration. It was not until June 16,1921, almost a month after first 

 eggs recorded we secured checks to identify these tadpoles. It was not until 

 July 8 ,we dared describe the coloration provisionally. On July 17, 192 1, we 

 recorded small tadpoles and only this size. In some ponds July 24, 192 1, the 

 tadpoles were almost a pure culture of Hylafemoralis and small. On July 26, 

 192 1, we finally decided the identification and described the coloration of 

 mature tadpoles. 



In 1922, June 26 "in an open pond were a series of Hylafemoralis tadpoles. 

 They have bright red in the tails of many of them, and long light Hne on the
