Thanks. I have the Burbrink article. I guess I need to thoroughly read it. But I guess my point that not everyone adheres to it. And is alleghaniensis inclusive of what were formerly known as black and yellow rats? Which I guess would mean Everglades, Gulf Hammock and Deckert's ratsnakes would just be considered geographic variations of alleghaniensis? Which isn't a surprise as many authors considered them geographic variations or intergrades before Burbrink's article.
