96 RANASYLVATICA. 



the throat and anterior part of the abdomen; yellowish-white on the posterior 

 part, and yellow near the thighs. 



The anterior extremities are short, coloured above like the back, with a dark 

 brown band running from the humerus towards the lower jaw, and another inter- 

 rupted black line on its posterior border. The forearm is blotched and sometimes 

 banded: the palms are more tuberculous than usual: there are four distinct fingers, 

 flesh-coloured on their inferior surface. The posterior extremities are extremely 

 long, coloured like the back, with regular transverse bands of darker brown con- 

 tinued to the feet; beneath, the thigh is flesh-coloured and granulated behind, white 

 and smooth in front, and yellow near the abdomen. There are five toes, fully 

 palmated, dark above and flesh-colour below. The tips of the fingers and toes 

 are slightly enlarged and obtuse. 



Dimensions. Length of the body from the snout to the vent, li^ inches; of the 

 thigh, 1 inch; of the leg, 1} inches; of the tarsus and toes. If inches; total length, 

 from the snout to the extremities of the toes, 5f inches. 



Geographical Distribution. The Rana sylvatica is confined to the Atlantic 

 States, and is found from New Hampshire to Virginia. 



Habits. This Frog is found, though not abundantly, in the woods of the 



northern and middle States, choosing thick forests of oak. It is active, and when 



^pursued, conceals itself among dried leaves, the colour of which it so nearly 



resembles as to be discovered with difficulty. In general it is found far from 



water, which it only approaches in the breeding season. 



General Remarks. We cannot find any notice of this animal previous to the 

 memoir of Leconte, where it is indicated under the very appropriate name of 

 Rana sylvatica, but not fully described. Harlan nearly at the same time published 

 a detailed and satisfactory account, in the tenth volume of Silliman's Journal.
