Hi,
Reading back I noticed this topic raised by Floridahogs. I'd like to pipe in though rather late. The bulletin of the Maryland Herp. Society Volume 4, Number 1, March 1968 (An Unusual Hognose Snake from Blount Island, Duvual County, Florida), reports a snake with the intermediate characters of H. simus and H. platyrhinos. External characters were intermediate on this snake, and to boot, so were scale counts. And to clinch the hybrid theory, the authors report that the snake laid 18 eggs all of which were infertile. Interesting.
