Vol. 37, pp. 141-152 December 29, 1924 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW BULLFROG (RANA HECKSCHERI) FROM GEORGIA AND FJ.ORIDA.' BY A. H. WRIGHT. In 1902 Dr. Leonhard Stejneger described Rana grylio, "A New Species of Bullfrog from Florida and the Gulf Coast" (U. S. Nat. Mus. Vol. XXIV, No. 1252, pp. 211-215). These southern bullfrogs, or ''Joe Browns" are very distinct in adult, tadpole and egg characters from the bullfrog, Rana catesbeiana. In the last ten years, evidence in the Okefinokee swamp region has presented enough material to warrant our description of a third bullfrog, Rana heckscheri from Georgia and Florida. It is as distinct if not more so than Rana grylio. In tadpoles, voice and adult characters it is clearly a new species. We have not the egg characters. Narrative : — On June 16, 1912, at the Fargo (Ga.) heronry amongst a swampy tangle of buttonbush (Cephalanthus occidentalis) , ''hurrah bushes" (Leucothoe racemosa) and "lather leaf" (Clethra alnifolia) the author found some black tadpoles with yellowish white crossbands and surmised that they were the tadpoles of R. grylio. That was a mistake. On the western edge of swamp on the day of our first entrance in 1912 we secured an adult frog which puzzled us. We saw it only for a few moments. We soon lost it in the rigors of the trip. It was a fine male of R. heckscheri. In 1921 when I returned from the swamp three tadpoles were iThe investigation upon which this article is based was supported by a grant from the Heckscher Foundation for the Advancement of Research, estabUshed at Cornell University by August Heckscher. The expense of its publication was borne in part by a second grant from the same Foundation. In the summer of 1921 Mr. Francis Harper assisted in the field work of this study and in the summer of 1922, Mrs. A. H. (Anna Allen) Wright, Mr. Francis Harper and Mr. Miles D. Pirnie gave valuable assistance to the author in this same series of studies. 26— Pboc. Biol. Soc. Wash., Vol. 37, 1924. (141)
