As none of the figures hitherto given of the genus Eophyton show either its internal structure, or articulations of its stems, and as I am in possession of a specimen from the Lower Arenig Rocks, of Ramsey Island, near St. David's, which resembles in some respects the Eophyton Linnœanum Torell, but which shows both articulations of the stem, and an internal vascular structure, a description of the species may probably be useful, and may tend to elucidate the true nature of Eophyton, concerning which so much doubt seems to exist at present.
page 535 note 1 So marked in the Geological Survey Maps. I am inclined, however, to tbink that they are representatives of the Tremadoc rocks, for Ling. Davisii, which is the only fossil present, is equally characteristic of Tremadoc rocks, and reaches here also into these Lower Arenig rocks.
