 The Cretaceous series is represented by two members only, Green- 

 sand with Orbitolina, and Baculite-limestone, on which latter rests the 

 Tertiary series, the lowest division present being the Middle Eocene. 

 Gives the following list of the Tertiary subdivisions of the Cotentin, 

 compared with British deposits : —

 The beds described are between the Exogyra-virgula marls and the 

 Ammonites-coronatus limestones, and consist (in descending order) of : — 

 1. Astarte limestones ; 2. Upper lithographic limestones ; 3. Chalky 

 limestone ; 4. Lower lithographic limestones ; 5. Marls and limestones, 

 with sponges ; 6. Marls, with pyritous ammonites. Of these divisions, 

 1 = L. Kimmeridgian, 2 and 3 = U. Corallian, 4 = M. Corallian, 

 5 = Argovian. The Oxfordian, altogether wanting in the Indre, is 

 represented in the Cher, Nievre, Yonne and Haute-Marne. One of 

 the chief points is the intercalation of the Argovian (Calcareous Grit of 

 British geologists) between the Oxfordian and the Corallian. G. A. L.
