The figure thus serves as an occurrence chart and also as a base for interpreting the Q- and R-mode clusters. Of the species that occur in biofaces A, relatively few are the principal contributors to the samples with significant numbers of specimens. The domi- nant elements (in terms of their relative abundance) are Hulingsina americana (Cushman, 1906), Puriana floridana Puri, 1960, and Hulingsina sp. E from the R-1 cluster of figure 8; "Haplocytheridea" bradyi (Stephenson, 193

Biofaces A and B are considered to repre- sent the northern part of the Carolinian faunal province and biofacies C, the southern part of the Virginian Province.
