War Department, 

 Office of Explorations and Surveys, February 14, 1859. 



The General Natural History Reports having been extended so much beyond the limits 

 originally contemplated, the War Department has considered it advisable to omit the publica- 

 tion of the Report on Reptiles. The plates to accompany this report having been prepared and 

 printed, they, with a brief explanation of the figures composing them, are herewith given. 



A. A. HUMPHREYS, 

 Captain Topographical Engineers, in charge.
