As in the northern Gulf basins, a considerable number of dead shallow- 

 water mollusk shells were found on sand bottom. These arrived there 

 either from slumping or as a result of lowered sea level during the Holocene. 

 A list of both living and dead invertebrates from this environment can be 

 found in Table I of the appendix, while the living species only (with 

 number of station occurrences) from the 15 stations taken on the upper 

 slope are listed below. Seven kinds of devices were used to establish this 

 assemblage (Table III), with various small dredges predominating. They 

 were: one orange peel grab, two rock dredges, three box dredges, five 

 shell dredges, one 12-meter and two 3-meter otter trawls. It can be seen 

 from this list that none of the species was taken frequently enough to 

 appear in the contingency matrix analysis. Relatively few individuals 

 were taken at any one station.
