FAMILY RANID^. QS 



Young. Olive brown, verging on green above ; the lateral stripe yellow, margined with 

 interrupted black lines ; the ocular stripe black, bordered beneath with white. Thighs, legs 

 and tarsus barred with black ; palms reddish. Beneath pure white. 



Length 2-5. 



This small species can at once be recognized in the woods by its amazing and quickly 

 repeated leaps, which render its capture difficult. 



It occurs from Massachusetts to Virginia, and is smaller than the Marsh Frog. It is said 

 by some authors to be confined to the Atlantic States in its range ; but we learn from Dr. 

 Kirtland, that they are so abundant in the woods in Ohio, that it is almost impossible to move 

 without stepping on them. It is allied to the R. temporaria of Europe, but is smaller, with 

 the head less pointed and tympanum smaller. 



(EXTRA-LIMITAL.) 



R. clamitans. (Holbrook, Vol. 3, pi. 17 ; and Vol. 4, pi. 20, 2d Ed.) Slender. Reddish brown 

 above, darker behind, silvery white beneath ; upper jaw green. Lateral cuticular folds. Length 

 three inches. Carolina, Georgia. 



Genus Cystignathus, Wagler. A sub-gular vocal vesicle, communicating with the mouth on each 



side of the tongue. Fingers and toes all distinct. Tympanum very small. 

 C. ornatus. (Holbrook, Vol. 1, pi. 16; and Vol. 4, pi. 25, 2d Ed.) Small. Dove-colored above, 



with oblong spots of dark brown, margined with yellow. Toes not palmate ; the two outer united 



at the base. South Carolina. 

 C. nigritus. (Id. Vol. 3, pi. 19; and VoL 4, pi. 26, 2d Ed.) Small. OUve brown; an interrupted 



black vertebral line, with blackish blotches along the sides ; legs barred ; upper lip white. Length 



1| inches. Carolina, Georgia. 



Genus Enoystoma. Fitzinger. Body oval, and covered with a smooth skin. Head small, pointed; 

 mouth minute. Tongue long, only movable behind. Jaws and palate without teeth. No 

 parotids ; tyropanum concealed. Fore legs with four, hind legs with five toes not palmated. 

 Obs. The animals of this genus bear a general resemblance to the Frog. Only one species has 

 been as yet observed in the United States. Dr. Holbrook thinks it possible that a species may be 

 found in this State, for he has heard its pecuhar noise in the neighorhood of New- York ; and Major 

 Le Conte informs me that he has seen a species of Engystoma, said to have been found in a sandy 

 district of this State. 

 E. carolinense. Holbrook, Vol. 1, pi. 1 1.) Chesnut above, and thickly mottled with blackish specks 

 beneath. South Carolina. '
