placed either in a single row, or aggregated like the rasp-teeth 

 in fishes. 



The skeletons, vestiges of the soft parts, and imprints of the 

 feet of several genera of Batrachians, occur in various tertiary 

 deposits, and, like the existing races, belong to fresh-water or 

 terrestrial species. In the pliocene strata on the banks of 

 the Rhine, and in the papierkohle of the Eifel, many speci- 

 mens of fossil frogs, toads, and newts, have been discovered. 

 But by far the most remarkable of the remains of this order 

 are obtained from (Eningen, and a specimen from that place, 

 deposited in the case whose contents are now under review 

 (ante p. 153), requires especial notice. 



FOSSIL SALAMANDER OF (ENINGEN. (Wall-case A-B.) 

 Among the tertiary lacustrine deposits of the continent, that 

 of (Eningen, near Constance, has long been celebrated for the 

 perfection and variety of its organic remains, and particularly 

 for Batrachian reptiles. A short, but graphic memoir, by our 

 distinguished countryman, Sir Roderick Murchison, presents, 

 in a few lines, the history of these ancient lacustrine deposits. 



The Rhine, in its course from Constance to Schaffhausen, 

 cuts through the tertiary marine formation, called the molasse, 

 which rises into hills from 700 to 800 feet high, on each side

of the river. On the right bank, a little above the town of 

 Stein, is the village of (Eningen, near which, in a basin, or 

 depression of the molasse, there is a series of deposits, com- 

 posed of laminated marls, and cream-coloured fetid limestone, 

 amounting in thickness to between thirty and forty feet.
