ResumoThe genus Eryon was established by Desmarest (in Brongniart and Desmarest's ‘Natural History of Fossil Crustacea:’ Paris, 1822) for certain forms of Astacidœ , with extremely broad and flat carapaces, found in the Lithographic stone of Solenhofen, one of the earliest known geological localities on the continent, and perhaps the most prolific in its yield of organic remains. Only one species was then determined—the Eryon Cuvieri of Desmarest ( Macrourites arctiformis of Schlotheim (1820), Locusta marina of Bajer (1757), and first figured by Knorr and Walch in 1755). Since that time Herr Germar, Count Minister, H. von Meyer, Professors M'Coy and Quenstedt have each contributed new species. Lastly, the late Dr. Albert Oppel, of the Royal Bavarian Museum, Munich, a Foreign Correspondent of this Society (whose early death we must all lament), has collected, revised, and added to our knowledge of this genus, so that in 1862 (the date of his book) the list of recorded species amounted to fourteen. Professor M'Coy was the first to record an English species of this genus, the Eryon Barrovensis , from the Lias of Barrow-on-Soar,Leicestershire. [See the ‘ Annals and Magazine of Natural History,’1849, p. 172.] But as his description varies in some points and is unaccompanied by a figure, I have ventured to delineate it by the help of the fine examples in the cabinet of the Rev. P. B. Brodie, F.G.S., and those in the British Museum. I also subjoin arevised description of it, and notices of other British species of this genus from
