A Synoptic Key to the Salientian Eggs of the United States

Abstract

Data for the present paper were gleaned from the examination of what preserved material has been available, almost entirely in the museum of Cornell University, a few specimens of fresh egg masses that the writers have been able to collect, and primarily, from the literature of previous authors. In the past only scattered notes on the eggs of the Salientians of this country were published and to date no comprehensive work has been done along this line. It is hoped that such an organization of information as is here presented will be of some use to other workers in the field. Furthermore, by pointing out a few of the difficulties, discrepancies, and lack of information regarding the eggs and egg laying habits of frogs and toads of the United States, it is hoped that others may find it worth their while to attempt to correct the existing state of affairs.
