124 HYLA SGIUIRELLA. 



The skin is smooth; the body short and depressed while living; the back is 

 olive-brown, with irregular blotches of darker olive; the flanks are grey. The 

 inferior surface of the body is granulated, greenish-white in front, with a few dark 

 spots at the throat; the posterior part of the abdomen is dai-ker. 



The anterior extremities are olive-brown above, with occasional dusky spots, 

 and flesh-coloured beneath; the fingers are four in number, distinct, and each 

 terminating in a viscous pellet. The posterior extremities are long, greenish 

 above, obscurely blended with dark brown, and flesh-coloured beneath, tinged with 

 yellow externally; the lower surface of the thigh is granulated; the toes are five in 

 number, and semi-palmated. 



Dimensions. Length of body and head, 1^ inches; of the thigh, f of an inch; 

 of the leg, I of an inch; of the tarsus and toes, to of an inch. 



Geographical Distribution. Its most northern limit must be considered as 

 latitude 34°, as I have no evidence of its being found farther north. It abounds 

 in South Carolina, Georgia, and Florida; — how far west of these states it may 

 exist cannot at present be determined. 



Habits. This animal is found on trees, often seeking shelter under the bark 

 of such as are decaying; it frequently chooses old logs for its place of hibernation. 

 Often I have found it about old houses, and under logs and boards. 



General Remarks. The colours of this animal are even more chano-eable 

 than in any species with which I am acquainted — I have seen it pass in a few 

 moments from a light green, unspotted and as intense almost as that of Hyla 

 lateralis, to ash-colour, and to a dull brown with darker spots; the spots also at 

 times taking on different tints from the general surface. The markings, too, 

 vary exceedingly in different individuals, the white line on the upper lip and the 

 band between the orbits alone are constant. Daudin remarks that the le<r is
