ZONE OF AEGOCERAS ANGULATUM. 



33 



Aeg. Moreanum, d'Orb., and Aeg. catenatum, Sow., Aeg. Liasicum, d'Orb., Aeg. laqueum, 

 Querist., Aeg. angulatum, Schloth., Aeg. C'/iarmassei, d'Orb. 



The workmen call the bed " Foie de Veau," and M. Martin 1 has adopted the local 

 name as equivalent to his Zone a Ammonites Moreanus, of which he has given an 

 exhaustive account in the memoir. M. Collenot 2 has likewise given a most able account 

 of the zone, with very full details of the Mine at Beauregard, and has very carefully 

 noted all the fossils that appertain to the " Foie de Veau," and placed them in separate 

 cases in the Museum of Semur, where I had the opportunity of examining them, and has 

 given the following list thereof in his exhaustive ' Description Geologique de l'Auxois.'
