In June 18.58 Dr. Giinther read a very valuable paper before the Zoological Society *, stating the principles according to which he was disposed to arrange, systematically, the Anurous Batrachians. The system therein offered is that adopted by the same author in his Catalogue of the Frogs and Toads contained in the British Mu-seum f. In 1865 Mr. E. Cope gave to the world another and very different plan for arranging the same animals J, a plan which he has amended and further elaborated in papers published in the ' Journal of the Academy of Natural Sciences of Philadelphia' §. Dr. Giinther's system reposes mainly on external and readily as-certainable characters. Mr. Cope's system is founded on certain points of osteological detail. I venture here to propose a classification which is derived from, and in all the most important points agrees with, that of Dr. Griin-ther, but which differs from it in certain minor respects (owing to a different estimate of the value of certain points of structure), while * Proc.
