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.
