_Skeleton of a reptile, allied to the Batrachians, in the Old Red Sandstone of Morayshire._--Mr. Patrick Duff, author of a "Sketch of the Geology of Morayshire" (Elgin, 1842), obtained recently (October, 1851), from the rock above alluded to, the first example ever seen of the skeleton of a reptile in the Old Red Sandstone. He has kindly allowed me to give a figure of this fossil, of which Dr. Mantell has drawn up a detailed osteological account for publication in the "Journal of the Geological Society of London." The bones in this specimen have decomposed, but the natural position of almost all of them can be seen, and nearly perfect casts of their form taken from the hollow moulds which they have left. The matrix is a fine-grained, whitish sandstone, with a cement of carbonate of lime. The skeleton exhibits the general characters of the Lacertians, blended with peculiarities that are Batrachian. Hence Dr. Mantell infers that this reptile was either a freshwater Batrachian, resembling the Triton, or a small terrestrial Lizard. Slight indications are visible of very minute conical teeth. Captain Brickenden, who is well acquainted with the geology of that part of Scotland, informs me that this fossil was found in the Hill of Spynie, north of the town of Elgin, in a rock quarried for building, and the same in which the Chelonian foot-prints, alluded to in the last page, occur. The skeleton is about four and a half inches in length, but part of the tail is concealed in the rock. Dr. Mantell has proposed for it the generic name of Telerpeton, from +tele+, afar off, and +herpeton+, a reptile; while the specific name Elginense commemorates the principal place near which it was obtained.

Reptile of Old Red Sandstone, from near Elgin, Morayshire.] _Eggs of Batrachians (?) in the Old Red Sandstone of Scotland._--At page 344. of this work I have given two figures (figs. 397 and 398.) of small groups of eggs, very common in the shales and sandstones of the "Old Red" of Kincardineshire, Forfarshire, and Fife. I threw out as a conjecture, that they might belong to gasteropodous mollusca, like those represented in fig. 399. p. 345.; but Dr. Mantell, some years ago, showed me a small bundle of the dried-up eggs of the common English frog (see fig. 524 _a_.), black and carbonaceous, and so identical in appearance with the fossils in question, that he suggested the probability of these last being of Batrachian origin. The plants by which they are often accompanied (fig. 398. p. 344.), I formerly supposed to be Fuci, but Mr. Bunbury tells me that their grass-like form agrees well with the idea of their being freshwater, and of the family Fluviales.
