The temperature was high and dropped 1° at a depth of 

 100 meters; the salinity rose and the hydrogen-ion concentra- 

 tion fell, both \ery slightly. Seventeen species were found at 

 the surface, 41 in the SO-meter tow, and 50 in the 100-meter 

 tow. Thirty-nine species (56 per cent) were each confined to 

 a single tow and 10 were found in all three tows. Corycaeus, 

 Farranula, and Oncaea were well di\ided among the three 



tows, but Oithona did not appear at all at the surface. Three 

 of the Candacia species, Eucalanus, Euchaeta, and Undinula 

 were present onl>- in the two deeper tows; Haloptilus, Hetero- 

 rhabdus, Lubbockia, and Lucicutia were confined to the 100- 

 meter tow. The 50-meter and 100-meter tows were each 3i 

 per cent longer than the surface tow and their proportionate 

 \olume corresponded exactly.
