North American Frogs and Toads

Abstract

THE life histories of North American frogs and toads form the subject of a memoir entitled “North American Anura—Life histories of the Anura of Ithaca, New York,” by Mr. A. H. Wright, just received from the Carnegie Institution of Washington. In the introduction to this highly interesting and well illustrated work the author acknowledges his indebtedness to Boulenger's-“Tailless Batrachians of Europe,” published by the Ray Society in I897–8, which has given the original impetus to and has been taken as the model for his study. The region investigated is at the southern end of Cayaga Lake, and most of the observations were made in the vicinity of Ithaca, New York. The number of Anurous Batrachians included within these limits is small, and only three genera, the widely distributed Bufo, Hyla, and Rana, are represented. The species are the common toad, Bufo lentiginosus americanus, the peeper, Hyla 25ickeringi, the tree toad, Hyla versicolor, the leopard- or meadowfrog, Rana pipiens, the pickerel frog, R. palustris, the green frog, R. clamata, the bull frog, R. catesbiana, and the wood frog, R. silvatica.
