Reference has been made in previous articles (1, 2) to the discovery of fossil fishes in the sandstone immediately overlying the basal conglomerate of the Keuper near Nottingham. The upper portion of this sandstone splits into slabs two or three inches thick along filmy partings of greenish clay. The specimen described and figured below was found lying upon the surface of one of these slabs with its head partially buried in the sandstone itself. After being carefully cleaned it proved to be a well-preserved specimen of Semionotus differing to a sufficiently marked degree from previously described species to merit the creation of a new species.
