The temperature was moderate at the surface and fell 

 nearly 7° in the 100 meters; the salinity and hydrogen-ion 

 concentration both diminished a little. Thirteen species were 

 taken at the surface, 63 in the 50-meter tow, and 63 in the 

 100-meter tow. Thirty-two species (40 per cent) were each 

 confined to a single tow and 7 were present in all three tows. 



Corycaeus was represented by 11 species and Oncaea by 10 

 species, and 19 of these 21 species appeared only in the two 

 deeper tows. Farranula, however, was distributed in all three 

 tows. There were 5 species of Haloptilus, 2 of Heterorhabdus, 

 and 3 of Oithona; all 10 species were confined to the two 

 deeiier tows.
