The Lower Lias is well developed in the Departments of the Meurthe and the Moselle, 

 in the east of France, in the Grand Duchy of Luxembourg, Belgium, and in the Dep. 

 Meuse. The fossils, from its different zones, have been collected with great care, and their 

 species determined, beautifully figured, and well described by MM. O. Terquem and Ed. 

 Piette in their valuable memoir. 1 In the valley of the Moselle a great number of Mollusca
