 Figures are the depths in feet at which the species occur.


 LOWER CRETACEOUS

 As already noted in the earlier report a number of the wells enter what seem to be Lower Creta'ceous limestones characterized by Orbitolina and lnumerotus other associated species. A table is given showing the distribution of these other species in the various wells where a species occurs in more than one well. As a rule these are from brownish crystalline limestones which come in below the Eocene represented by the abundant Numnutlites. The conical and broader concave forms are present in a number of the wells and their relations have been noted in the earlier report.
