 fms. OPG took 0.44 cuft of fine green sand with many small animals. 

 Gross weight was only 17.4 grams, of which polychaetes were 10.1 and 

 ophiuroids 5.5 grams. A polyclad (1), a nemertean (25), Glottidia 

 albida (151), 13 kinds of amphipods (172), three isopods (12), two 

 tanaids (21), five ostracods (151), five cumaceans (23), Heterocrypta
