The plankton along the outer part of the con- tinental shelf, south of Delaware Bay (Stations 10073, 10074) was also of this type. In the Gulf of Maine mixed plankton was encountered on German Bank (Station 10095); near shore east of Mt. Desert Island; and again north of Cape Ann (Station 10105). There were.
