E V I O R A Mmseiiiiini of Comparative Zoology Cambridge, Mass. April 6, 1956 Number 52 REMARKS ON SOME MIOCENE ANURANS FROM FLORIDA, WITH A DESCRIPTION OF A NEW SPECIES OF HYLA By Walter Auffenberg Up to now, the only reference to Miocene anurans from Flor-ida is by Tihen (1951), who described a new species of Bufo and allocated other remains to Rana sp. All of these fossils were collected at Thomas Farm, Gilchrist County, Florida. While washing a considerable amount of matrix from this same deposit in search of fossil snakes, a rather large number of amphibian remains were found, and these form the basis of this report. The new material permits addition of three more genera to the fauna of the Miocene, and also contributes to a better understanding of the relationships of the previously described Bufo. Bufo praevius Tihen This toad was described on the basis of fragmentary elements of both the axial and appendicular skeletons. The relationships of B. praevius were not discussed at length by Tihen, although he stated that the ilium is somewhat comparable to that in B. terrestris and B. valliceps. Considerable additional material from the same deposit contributes to our knowledge of its prob-able relationships. Of particular interest is the fact that there are now available cranial elements, generally considered to be quite diagnostic between species of toads. This is especially true of the orientation and degree of development of the various cra-nial crests. Information regarding these structures is now avail-able for praevius. The systematic relationships of many of our North American toads have been the subject of considerable controversy during
