" It will be perceived that the fossils of this deposit are 

 tertiary, and that not one is common to the underlying chalk, 

 with which it appears some French geologists had classified 

 it." M. D'Orbigny, who designates this deposit under the 

 name of Calcaire plsolitique tertiaire, then mentions several 

 localities in which it occurs, in the vicinity of Paris, as at 

 Bougival, Port Marley, Vigny, and Auteuil. He also consi- 

 ders the shelly beds of calcaire grossier of Laversine, near 

 Beauvais, as the equivalent of the same stratum. 



A pit recently excavated at Montalets, Bas Meudon, led 

 M. Chas. D'Orbigny to discover a series of new and interest- 

 ing strata immediately overlying the above-mentioned cal- 

 caire plsolitique (see section, p. 190), and from the chalky 

 conglomerate No. 6, he obtained the following reliquice : —
