July 16, 1851. 



Dr. C. T. Jackson, Vice-President, in the Chair. 



Mr. H. R. Storer read from a letter from Dr. Burnett, 

 some memoranda of observations made by him, during the 

 past ^winter and spring at Aiken, Ga., on the Reptilia of 

 that region, as follows : 



Lygosoma lateralis is quite rare ; I saw but a few specimens. 

 I could ascertain nothing of its habits. It is found only in damp 

 places. The breeding season there is the middle of March. 



Tropidolepis undulatus is by far the most common of all the 

 caudate Batrachians of South Carolina. It is even more com- 

 mon than the Common Toad, (Biifo Americanus.) Sunny days 

 it is met with everywhere on rail fences, but seems to avoid wet 

 or damp places. It appears to pass the winter beneath the bark 

 of trees, and does not attain its adult condition until the second 

 year at least. Its breeding season does not begin until April. 



Anolius Carolinensis is much less common and more domestic 

 in its habits, for it appears to delight in living about a house. 

 Otherwise it is closely allied in habits to the latter, and breeds at 

 the same season. It appears to reach its growth the first year. 

 As far as I could ascertain, the bright green color seems to be 

 due to a vascular turgescence, pressing the green dermis forcibly 

 to the light. For when depressed by fear, a flabbiness of the 

 integuments occurs, and the color recedes, giving place to the 

 brownish aspect of the epidermis. 



Ameiva sexlineata. Quite rare, and the most agile of this 

 class of animals I have seen. They are found in pairs in dry
