Ilylrrpelon Dawsoni, Owen. In the more or less laminated material which fills the interior oi the erect trees of the Joggins, it often happens that the more distinctly separable surfaces arc stained with ferruginous or coaly matter, or with fine clay, so that the fossils which occur on these surfaces, and which would otherwise be more available than those in more compact material, arc rendered so obscure as readily to escape observation. This was unfortunately the case with one of the most interesting specimens contained in the last of these trees which I had an oppor- tunity to examine. It consisted of the detached bones of a reptile scattered over a surface so blurred and stained that they escaped my notice until most of them were lost; and I was able to secure only a jaw bone and fragments of the skull, with a few of the other bones. On these fragments Professor Owen founded the genus Ilylerpeton and tlie species named at the head of this article. His description is as follows (Fig. liT) :â Kig. 147.
