The Muschelkalk fauna has been thoughtto indicate that the sea in which it lived was not the open ocean,but rather a body of water comparable to the Black Sea or the the name indicates, limestone makes up the larger part of theformation. The third formation, the Keuper, resembles the first, and, like it,is marine in its upper portion, and is followed by the marine beds of.

England.—The chief point of difference between the Trias of Ger-many and that of England lies in the fact that the marine memberof the former is absent from the latter. Otherwise the system cor-responds in the two countries, so far as general characters areconcerned. The absence of the marine division from the system in 1 Kayser, op. cit., p. 286. •0>t GEOLOGY.
