Indeed, the primitive taxonomist Linnaeus excluded snakes from Reptilia, = and he included Reptilia, along with lampreys, sturgeons, sharks, and = other non-tetrapods in Amphibia.

Not quite an accurate read of folk taxonomy. While it is true that most cultures recognize a category "bird" (which often includes bats), I can't think of a folk taxonomy that recognizes a "Reptilia" sensu Romer and company (i.e., a group comprising turtles, lepidosaurs, crocs, and nothing else in the living world). These critters tend to be lumped in the = general quadruped catagory, and are not brigaded off in a particular section exclusive of mammals. Indeed, Linnaeus himself had some rather peculiar combiantions of taxa in his Amphibia (Reptilia)... Thomas R.
