Summary[edit] Description: English: To show possible coloration of some North American Hylas. In all cases not only is there great power of change, but any pattern of spots or bands on the top of the head and on the back is evanescent in character. Fig. I. -THE SPRING PEEPER {Hyhi pickeringii Sior&r. Providence, R. I.] Varies through many shades of ashy or yellow brown. Figs. 2 and 3.— THE GREEN TREE FROG [Hyhi cijtnra Daudin. Ft. Myers, Florida]. May be green or brown, but is always known by the light bands. Fig. 4.— THE SOUTHERN TREE FROG [Hyla squirella Bosc. Hitchcock, Texas]. Figs. 5 and 6.— THE SOUTHERN TREE FROG. Havelock, N. C. These tree frogs vaiy through all shades of green, gray and brown, and may be spotted or not. Fig. 7.— THE FLORIDA TREE FROG IHyla gratiosa LeConte. Orlando, Fla.]. May be green or brown, spotted or not. It is often found with the change from green to brown in process, in which case the frog is green conspicuously spotted, but with brown gradually replacing the green on the back.
