[Metz, Société d'Histoire naturelle du Département de la Moselle, 1847]. 8vo (22.3 x 14.3 cm). 60 pp., three engraved plates. Contemporary blind quarter cloth over paper-covered boards.

Rare offprint from the society's Bulletin of this important paper on a new, mosasaur-like reptile, based on a well-preserved skull found in northeastern France. Sometimes the naming of the new species is supposed to be done by Pascal Monard, but the paper offers no clue to this. Although no-where indicated this copy is from the Moquin-Tandon library. The French naturalists, malacologists and palaeontologists Olry Terquem (1797-1887) and Christian Horace Benedict Alfred Moquin-Tandon (1804-1863) both wrote much on the natural history of France. Light wear to the boards, otherwise a very good copy. Not in Cat. BM(NH), where several other Terquem titles are listed.
