 OPG took 0.31 cuft of fine gray sand with many small animals. Weight 

 of animals was estimated at 19.2 grams, of which polychaetes comprised 

 9.3, ophiuroids 7.1, and mollusks 2.5 grams. In addition to those listed 

 on the chart, there were present a small nemertean (9), a phoronid (1), 

 Glottidia alhida (131 juveniles), nine amphipods (43), a tanaid (7), 

 two ostracods (29), three cumaceans (5), Callianassa sp. (1), and a pin- 

 nixid (5). The largest individual was Astropecten calif ornicus, the most 

 conspicuous species Amphioplus hexacanthus (88), and the most abun- 

 dant Glottidia albida (131) and Chaetozone corona (88*).
