I agree and must say that they are probably the most interesting and beautiful python species that I have worked with over the years. From the information that I have been able to gather, I believe these may indeed be related to the Dehiwela Zoo specimens you were working with. If you do run across what you believe are pure specimens, I would be most interested to see them. Also, I've heard that the zoo in Dehiwela is quite impressive. Thanks again,
