Poisonous snakes are only one aspect of the study of herpetology, which includes other reptiles, as well as amphibians. These together may be referred to as herptiles. There are 97 species of herptlles in Kansas: 9 salamanders, 20 frogs and toads, 15 lizards, 40 snakes, and 13 turtles. The turtles of Kansas have been described in a past issue of The Kansas School Naturalist (April, 1956), and an issue on the lizards of the state is in preparation.
