C. ornatus. Cystignathus ornatus Holbrook 1. c. pi. 25. 



Body short and broad. Above smooth, pale brown or dove or slate color, 

 with numerous specks of black. Lips whitish, yellowish or flesh color. Irids 

 golden. Tympanum small, black, distinct. Top of the head with a large, ir- 

 regular, triangular, dusky spot, the base of which lies between the eyes, and the 

 apex points backward, this with a long stripe of the same color on each side of 

 the vertebral column is sometimes very distinct, at others not visible. A black 

 vitta extends from the point of the nose through the eye and tympanum to near 

 the insertion of the arm, ana is sometimes continued on until it joins another 

 which runs along the sides to the middle of the body ; there are one or two 

 spots of the same color towards the hind part of the body, frequently however 

 wanting ; when present all these black maiks are bordered by yellow or white. 

 Beneath except on the throat cancellately reticulate, white or yellowish with 

 numerous black specks assembled in irregular groups. Legs above with trans- 

 verse bands of darker or dusky, thighs behind granulate and often spotted with 

 yellow ; there is generally a black spot on the outer part of the shoulder. The 

 tongue in this species is much rounder than in the preceding, it is also more 

 slightly emarginate and less narrowed at the base. 



Length 1.3 in., leg 1.8, tibia and foot 1.2. 



Inhabits Georgia, very common in the pine barren ponds.

Body very broad and blunt, above covered with small warts ; beneath every 

 where granulate, the granules on the throat and chin are so Email, that these 

 parts appear almost smooth, tibia beneath reticulate. The color above varies at 

 will from pale brown to different shades of ash and to green, with a few irre- 

 gular spots or blotches, variable both in color and in form, which at times are 

 so arranged as to assume the appearance of an oblique angled cross ; there are 

 also numerous specks of black on different parts of the body. Beneath the 

 color is white, the inner and hinder sides of the thighs are of a deep yellow or 

 orange color, the under side with that of the tibia deep flesh color, both of them 

 reticulate with black. 



Inhabits from New York to the lower and warmer parts of Georgia, where 

 however it is very rare. 



This animal is the analogue of the Hyla arborea of Europe.

Body rather narrow and elongated. Varies in being above of various shades 

 of green sometimes nearly black, the green color however being by far the most 

 common, the other marks are constant. The line on the sides is either yellow 

 or silvery. In the spring it is found in rice-fields in astonishing quantities. Is 

 commonly known by the name of the bell-frog, its notes resembling the sound 

 of small bells. It is frequently called the fried bacon frog, as its voice seems to 

 some ears to repeat those words. Laurenti considers it as a variety of Hyla arborea 

 which he calls viridis, although it had borne the former name for many years 

 before he wrote his synopsis. Our American animal has but little resemblance 

 to the European, especially in form.

The darker marks on the head and back are sometimes evanescent, but the 

 yellow spots on the hind part of the thighs are always more or less distinctly 

 visible. The chin is cancellately reticulate, sometimes speckled with dusky 

 sometimes altogether of that color. The color of the body above varies at the 

 will of the animal.
