Inhaltsangabe

Excerpt from On the Structures and Distribution of the Genera of the Arciferous Anura<br/><br/>The occurrence of a xiphisternal style similar to that of the Ranidae, may be re garded as an indication of superiority, not only in consideration of this affinity, but as a greater degree of specialization and ossification of the part. It appears, how ever, not merely among the most Raniform Arcifera, but among some with prolcoelian vertebrae, which have the salamander-like mode of reproduction, and also among some of the opisthocoelian species. Notophthalmus viri d e s c e n s lays its eggs singly on leaves, e. G., at the union of the capillary segments of Myriophyllum, or along their length, pressing them together on the egg as it is deposited. They adhere closely to its gelatinous surface, and serve to conceal it.
