shells of a few dead ones— mostly scallops— were 

 8 to 9 centimeters long. 



Except for one sample of gravel, the substrate 

 at all of the stations was predominantly muddy 

 (silt-clay), but generally included varying pro- 

 portions of coarser materials — usually gravel; 

 coarse, medium, or fine sand; fragmented shell 

 remains; or combinations of these materials.
