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 =
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)...
