The USF&W Service's Notice of Inquiry says "we are looking at obtaining information on constrictor species in the Python, Boa and Eunectes genera for possible addition to the injurious wildlife list under the Lacey Act." (my emphasis)

So this wouldn't include, among others, carpets or GTP's? They're in family pythonidae but in genus morelia, at least for now. And how could the introduction of the rubber boa be harmful when it's already native to the northwestern U.S.?

Doesn't sound like much thought has been devoted to the proposed new regulation (right, nothing new) and I seriously doubt that the drafters had a clue about the larger domestic, captive bred ball python scene.

Obviously everyone must take this seriously and respond with vigor and alarm, I'd be stunned if any regulation went further than Burmese Pythons -- due to the Everglades problem -- and maybe other of the largest snakes.

Something else that might be going on here is a sort of stealthy response to complaints about the whole pet reptile pet scene, fueled to a a degree by the usual irresponsible sellers and buyers.
