Do you mean amethystine python? if so same species just another name.
Australia's largest python is the Amethyst (or Scrub) Python Morelia amethistina (above). It is a python of tropical rain forests, mostly nocturnal in habits and sometime concealing itself in trees. Apparently Harvey et al. (2000) proposed splitting this species into at least three, including M. clastolepis on Ambon and M. kinghorni in NE Queensland (Cape York Peninsula, several Islands of Torres Straits). These splits are apparently based on an "evolutionary species concept." I presume that the one I photo'd (above & left) is still M. amethistina as it was on the Atherton tablelands, but Cape York Peninsula is not far away. My friend John Sullivan has photos of a couple other Australian pythons, and an Amethyst from the Cape York Peninsula.
Taken from a website as I got warned not to put links up lol.
