Off Chesapeake Bay (Station 10076) the numbers in the deep and 
shallow hauls were more nearly equal. In the edge of the Gulf Stream, 
south of Long Island (Station 10064) compressa was ten times as 
—————— 
numerous in the haul from 175 fathoms, as in the twenty fathom haul. — 
Euthemisto bispinosa like compressa was more abundant in the 
deep than in the shallow haul at Station 10064. And it was likewise 
several times as numerous in the shallow as in the deep haul in the 
eastern part of the Gulf of Maine (Station 10092). But it was about 
equally numerous in the two hauls at Station 10061; and off Chesa- 
peake Bay it was most numerous in the deep haul.
