(2) The species followed by an asterisk have been noticed in the text 

 and plates of my " Paleontologie frangaise," as belonging to the gault. 

 I have since perfectly convinced myself, during a journey in the Depart- 

 ments of Aube and Haute-Marne, that they all belong to the upper Ne- 

 ocoraien formation, or the epoch of the Ammonites of Garges, near Apt, 

 which, in Provence, is the equivalent to the clay a plicatules of Haute- 

 Marne and Aube.
