Description of a neiv species of Hylafrom Georgia. 

 By John Le Conte. 



During the last spring, whilst I was residing in the lower country of Georgia, 

 it was my good fortune to meet with three specimens of the animal described 

 below. One of them was taken in the water of a pine barren pond, another 

 was found in a cavity of a sand pit, and the third upon a tree in the forest. 



This Hyla is remarkable for its size, approaching in this respect to those 

 found in tropical regions. Two of them were of a greenish dusky ; the second, 

 who had concealed himself in a hole in the sand, was of a bright pea green, but 

 in the space of half an hour changed to the color of the others, thus showing a 

 complete possession of the faculty of changing color at will, so remarkable in 

 many of the Batrachia. 



There yet remain undiscovered and undescribed, in Georgia, three species of 

 this genus, which have as yet eluded my search. The notes of these are re- 

 markably distinct from those of others ; I may hereafter be fortunate enough 

 to obtain them. 



Hyla gratiosa. 



Coarsely granulate both above and beneath. Color above varying at the will 

 of the animal from bright green to cinereous and to greenish dusky, with round- 

 ish spots or irregular blotches of darker, or speckled with variously shaped 

 dots of the same, all of them with some few small yellow irregularly disposed 

 spots on the back and sides. Beneath whitish, more or less inclining to yellow 

 or orange. Upper lip white, or white varied with green or dusky ; lower lip 

 sometimes whitish, at others of the color of the back : in some a white line ex- 

 tends from the upper lip along the side to the insertion of the hind leg, in others 

 the sides are variegated with rounded spots of darker, and no line visible. Irids 

 black varied with golden ; tympanum copper-colored, a considerable depression 

 between the nostrils and the eyes. Chin varied with dusky or green, with a 

 slight fold at the bottom ; transverse space between the arms smooth, without 

 any granulations. Arms and legs barred, with darker, yellowish or reddish on 

 the under side, the former smooth beneath, the latter granulate on the poste- 

 rior half; the under side of the posterior half of the thighs is smooth. Disks of 

 the toes very large. 



Length of head and body 2-5 inches ; humerus -6 ; autibrachium -6; hand -75; 

 femur 1-2 ; tibia 1-15 ; foot 1-6. 



Notes on the Reptiles in the collection of the Museum of the Academy of Natural Sciences. 



By Edwaed Hallowell, M. D. 



It is not surprising that, among the reptiles of the Academy, which it has 

 required more than forty years to bring to its present although incomplete con- 

 dition, and which is now for the first time in process of classification and 

 arrangement, there should be many new species that do not appear to exist 

 even in the large European collections. It is possible, however, that some of 

 these may be mere varities, or they may be already known ; but after careful 

 inquiry, I have not been able to make them out as such, and the interests of 

 science,' it appears to me, will be best subserved by their publication, even should 

 the account of them hereafter be found to contain a few errors. 



Fam. CAMELEONID^.

Among the Cameleonidse in the collection of the Academy, we find two which 



differ from any of those described in the work of Dumeril and Bibron, and in 



the Memoir of Prof. Aug. Dumeril, in the Archiv. du Museum, tome vi., p. 210. 



Neither are they found in the Catalogue of the Lacertians of the British Museum,
