Restorations of some of these extraordinary creatures have been attempted in the guise of colossal Frogs; but they must in reality have more closely resembled huge Newts. Remains of Reptiles are very abundant in Triassic deposits, and belong to very varied types. The most marked feature, in fact, connected with the Vertebrate fauna of the Trias, and of the Secondary rocks in general, is the great abundance of Reptilian life. Hence the Secondary period is often spoken of as the "Age of ; Many of the Triassic reptiles depart widely in their structure from any with which we are acquainted as existing on the earth at the present day, and it is only possible here to briefly note some of the more important of these ancient forms. Amongst the group of the Lizards {Laceytilia\ represented by Protorosaurns in the older Permian strata, three types more or less certainly referable to this order naa}^ be mentioned. One of these is a small reptile which was found many years ago in sandstones near Elgin, in Scot- land, and which excited special interest at the time in conse- quence of the fact that the strata in question were believed to belong to the Old Red Sandstone formation. It is, however,.
