LOWER CRETACEOUS 



As already noted in the earher report a number of the wells 

 enter what seem to be Lower Cretaceous limestones characterized 

 by Orbitolina and numerous 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 NiiininuUtcs. The conical and 

 broader concave forms are present in a number of the wells and 

 their relations have been noted in the earlier report.
