Vol. XV, pp. 235-238 December 16, 1902 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON SOME GENERIC NAMES OF TURTLES. By LEQNHARD STEJNEGER. I. Merrem, in 1820, (Tentamen, p, 27) was the first author to give a generic name, viz: Terrapene, to the Emydine turtles with a movable plastron, which some earlier writers, such as Oppel (1811) and Cuvier (181*7), had indicated as a section of the genus Emys. In the genus he included six valid species (his T. boscii being only a synomyne of T. ornata) as follows: (1) T. odorata (+ boscii), (2) T. pemisyhianica, (3) T. ambointnsis, (4) 7'. tricarinata, (5) T. idgricojis, • (6) T. clausa. Two years later Fleming (Philos. Zool. II, p. 270) appar-ently without knowing Merrem's work, gave the name Cistiida to the same group of turtles, without mentioning any species whatsoever. This makes it an unconditional synonym of Ter-rapene, a conclusion quite in consonance with Say's use of Fleming's name in 1825 (Journ. Phila. Acad., IV, ii, p. 205) for the species C. clausa, C. pennsylvanica, and C. odorata. In 1824, Spix (Testud. Brasil., p. 17) instituted the genus Kinosternon, thus taking out of Merrem's Terrapene his T. tri-carinata. J. E. Gray in a paper entitled "A Synopsis of the Genera of 45— Biol. Soc. V^ash.
