Except the above mentioned corals, all the corals are new 
species ; but they are, with very few exceptions, identical with 
the species found in the Lower Claiborne of Alabanui and 
Mississippi. 
The presence of such mollusks as Ostrea divaricata, O. sel- 
Ifeformis, Anomia e/>///y>//o/V/c.v, Borsoitia hicouic((, Latirus 
moorei, Fiatns mortoniopsis, etc., leaves no doul)t as to what 
the homotaxial equivalents in Mississipi, Alabama, and Texas
