The workmen call the bed " Foie de Veau," and M. ]\Iartin^ has adopted the local 

 name as equivalent to his Zone a Avu)wnites Moreanus, of which he has given an 

 exhaustive account in the memoir. M. Collenot" 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 I'Auxois.'
