Abstract Descriptions are given of the tooth skeleton of two species of Gnathostomata. Fundamental differences in the constructions of tooth elements of Gnathostomata compared with those of regular sea urchins are discussed. In the author's opinion the teeth of Gnathostomata are not to be derived from the teeth of any order of post paleozoic regular sea urchins, and the Gnathostomata is thought to be a monophyletic group of its own.
