14 BUFO aUERCICUS. 



of the posterior part of the orbit of the eye; a small part only of the orbit in 

 front of this is light coloured; the upper jaw is light brown. 



The back of the animal is dusky-brown, with a vertebral line of pale yellow, 

 marked with a few scattered small warts of reddish-brown colour; on each side of 

 this line are irregular black blotches, with here and there a slight tinge of reddish- 

 brown; the back is covered with innumerable warts and granulations, of variable 

 size and colour, generally black, but the smaller ones of dusky-red; on each flank, 

 and extending from the axilla downwards towards the posterior extremity, is an 

 oblong black blotch, bounded with white both above and below. 



The throat is dusky; the abdomen silver-grey, yellowish at the groins, and with 

 a pale tinge of yellow around the vent. The anterior extremities, as well as the 

 posterior, are dusky-brown above, marked with black transverse bars or spots; 

 their inferior surface is coloured like the abdomen, except the fingers and toes, 

 which are reddish-brown. 



Dimensions. Length of the animal from the snout to vent, | of an inch; length 

 of thigh, 5 lines; length of leg, 5 lines; length of tarsus and toes, 65 lines. 



Habits. This beautiful little species of toad is mostly found about sandy 

 places that are covered with a small species of oak, which springs up so 

 abundantly where pine forests have been destroyed; whence it is commonly 

 enough called the Oak Frog, which specific name I have preferred. It spends 

 most of its time in concealment under fallen leaves, or partially buried in the 

 sand, from which it is washed out by heavy rains. In the breeding season they 

 seek out stagnant pools, where they deposit their spawn, during which time the 

 male makes a slight chirp, not unlike some kinds of insects. 



Geographical Distribution. As yet the range of this animal seems very 

 limited: I have only found it near Charleston in South Carolina, and at Smithville
