The specimen which forms the subject of the present notice belongs to the genus which is termed by some authors Trachyteuthis, and by others Coccoteuthis. Both names were originally given to the internal shell of a Sepia-like Cephalopod; the former to examples from the Lithographic Stone (Lower Kimeridgian) of Bavaria, and the latter to a specimen from the Kimeridge Clay of Dorset. They are regarded as synonymous, but some authors use one and some the other.
