and September when the species was active. On October 9, 1906, Mr. A. G. 

 Hammar secured three one year olds at Jennings, La., and we have another 

 record of transformation in October, 1915. 



AFFINITIES 



Holbrook (1842, Vol. IV, pp. 121, 122) reviews this in detail. According 

 to him Linnaeus held it a form of Rana arborea and credited it to Europe as 

 well as America {Rana arborea var. B.) Laurenti called it a variety of the 

 European Hyla viridis. Gmelin considered it a variety of Rana arborea. 

 Schneider called it a variety of Calamita arborea. Daudin pronounced it a 

 distinct form as does Holbrook, 1842, and LeConte 1856. The latter writes 

 (1856, p. 428) "Our American animal has but little resemblance to the Euro- 

 pean, especially in form." 



Like Hyla gratiosa, Hyla femoralis, Hyla versicolor, Hyla cinerea has 

 indefinite outer envelopes. In egg deposition it may be between Hyla 

 gratiosa and Hyla andersonii group and the surface surface film group of 

 Hyla versicolor and Hyla femoralis. In some ways we incline to a closer re- 

 lationship with the former group. In tadpole mouth parts we placed it with 

 the Hyla gratiosa, Hyla andersonii group with their short 3rd lower labial 

 tooth row in contrast to the long 3rd lower labial row of teeth in Hyla squir- 

 ella, Hyla femoralis, and Hyla versicolor. In tadpole coloration and general 

 appearance it is more suggestive of Hyla gratiosa although the crests are 

 quite different. Of the American Hylas it seems all in all nearer Hyla ander- 

 sonii and Hyla gratiosa and somewhat approaching Hyla squirella.
