The surface temperature was low and fell almost 50 per the 100-meter tow. Twenty-four species (75 per cent) were 



cent in the 100 meters; the salinit>- and hydrogen-ion con- each present in a single tow and 2 in all three tows. Cory- 



centration changed comparatively little. Six species were caeus, Eucalanus, and Oncaea appeared in the two deeper 



taken in the surface tow, 16 in the 50-meter tow, and 22 in tows, Farranula only at the surface, and Oithona in all tows.
