In September of last year I received from Mr. Howard Fox, F.G.S., of Falmouth, nine specimens of Trilobites for the purpose of determination and description. They are all more or less fragmentary, and distorted by slaty cleavage, as is usually the case with fossils from these Devonian Slates of Cornwall and Devon, reminding one of the distorted Trilobites and Starfishes from the Lower Devonian Slates of Bundenbach, Germany.
