The specific identity of the larval B. gracilis with the adult B. amblystomus, of the Rothliegendes of Saxony, is admitted by their describer3; while the impossibility of separating the former from the larval P. petrolei of the corresponding beds of Prance was pointed out by Geinitz and Deichmuller4. Hob. Europe (France, Saxony, and Thuringia). R. 489. Fragment of shale showing the skeleton of a larva; from the Eothliegendes (Lower Permian) of Millery, near Autun (Saone-et-Loire), France.

Protriton salamandroides (Fritsch5). Syn. Branchiosaurus salamandroides (Fritsch 6). The type of Branchiosaurus. Distinguished from the preceding species by the stouter vertebrae of the larva, in which the proportion of the width to the length is 1 to 8 instead of 1 to 13. The trans- verse processes of the vertebrae are also stouter and wider. Hob. Europe (Bohemia). 1 Zeitschr. deutsch. geol.
