XIII. Reptiles from the Elgin sandstone.—Description of two new genera

Since the reading of my previous paper (68), ‘On some New Reptiles from the Sandstone,’ several additional specimens have come to me for examination, by are all from the Elgin Sandstone, but, with possibly one exception, are from the at Spynie, two miles north-east of Elgin. Two of these specimens are new as, representing two new genera, and form the subject of the present communicao. One of them, like all those in the earlier paper, is in the condition of hollow, and a similar mode of investigation has been resorted to, namely, the preation of gutta-percha casts from the cavities. In the second specimen the bones present, but in a very friable condition; the skull, however, owing to the care which it was uncovered by Mr. Richard Hall, of the British Museum, is now utifully preserved, and most of the caudal vertebrae are still in situ; but the gater part of the rest of the skeleton had hopelessly crumbled away with the taking open of the stone, and, for these parts, the casting process had again to be orted to before the forms of the bones could be seen.
