Hyla squirella 323 



1901, P. R. Paine at Charleston, S. C, took 16 specimens (U. S. National 

 Museum No. 29229-29243) 17.5, 17.5, 19, 19.5, 20, 20, 20, 20.5, 21, 22, 22, 23, 

 23, 23, 24.5, 25 mm., respectively 17.5-25 mm. William Wittfield took (U. S. 

 National Museum No. 12008) twelve specimens 15, 16, 19, 21, 24, 24, 25, 25, 

 26.5, 27.5, 28, 28.5 mm. respectively. Material taken by Professor A. M. 

 Reese, Lake Kissimee ranges from 20-27 mm. (one 31 mm.) for 23 specimens, 

 (U. S. N. M. Nos. 36202-10, 29065-66, 36249-36260), an average of 23.5 mm. 

 All combined it seems as if 11-14 mm. is transformation size, 17.5-25.5 mm. 

 is one year old size, 25-35 mm. is two year old size. 



Very recently we discovered considerable material in the U. S. National 

 Museum from one locality, Charleston, S. C. in the fall of 1923 and the 

 summer and fall of 1924. They were taken by J. T. Rogers as follows. On 

 June 19, 1924, he secured (U. S. N. M. Nos. 67425-42) all adults 23-33 mm- 

 (Males 24, 25, 25, 27, 27, 28, 28, 33; females 23, 24, 24, 25, 25, 25, 26, 26, 30) 

 — all possible two year olds 23-33 i^i^- but the 30 and 33 mm. individuals are 

 possibly apart. On Sept. 17, 1924, J. T. Rogers took (U. S. N. M. Nos. 67714- 

 67730) the following: 14.5, and 17, 18, 18, 18, 19, and 21, 22, and 26.5, 27, 27, 

 27, 28, 28, 28, 29, and 32 mm. Have we three groups, 14.5 mm., 17-22 mm., 

 26.5-32 mm.? On November 16, 1923, Rogers took 4 specimens (U. S. N. M. 

 66804-7) i7-5j 20, 20, 22 mm. Does all this material shape as follows: 14.5 

 mm.; 17-22 mm.; 23-30 mm.; 32, 33 mm.? 



After measuring the American Museum material their data seems to fall 

 thus: 13 mm. transformation; 19-23 mm. or 25 mm. for the first year olds; 25 

 or 26-36 mm. for 2 year olds. Several specimens from 19 to 23 mm. or in one 

 instance 25 mm. we recorded as doubtful in sex. Doubtless they were all one 

 year olds. But the males and females clearly so externally 23-25 mm. are 

 doubtless individuals older than one year. 



FOOD 



Deckert (192 1, p. 22) in Miami, Dade Co., Florida, finds that "A few have 

 established themselves in the velvet bean vines covering the writer's back 

 porch, and at night will sit flattened out against the window panes, catching 

 the insects that are attracted by the light within." 



ENEMIES 



On June 27, 1922, in one pond "we found a Hyla squirella tadpole with 

 one hind leg. Yesterday found one tadpole with forelegs about to burst out 

 but it had no hind legs. Either lost or never developed." In this pond we 

 took southern riband snakes and chicken turtles {Deirochelys). 



AUTUMNAL DISAPPEARANCE 



Deckert (192 1, p. 22) records them after heavy rains in September in 

 Dade County, Florida. Pope (19 19, p. 97) at Houston, Texas, heard it as 

 late as September 20. "Have heard very httle of Hyla squirella lately, but 

 rain fell all last night and tonight they were singing loudly again, although it
