The temperature, salinit>-, and hydrogen-ion concentration 

 were all high and practically unchanged at the two depths. 

 Eleven species appeared at the surface and 27 species in the 

 SO-meter tow. Twenty-four species (75 per cent) were found 

 in one tow and not in the other, and 7 species were present 

 in both tows. Euchirella and Megacalanus were found only 



in the deeper tow; the other four deep-water genera did not 

 occur at all in this locality. Corycaeus and Farranula were 

 divided as before between the two tows, and the 2 species of 

 Farranula constituted a large percentage of the surface tow, 

 but Oithona, except for 2 specimens, and Oncaea were not 

 present at the surface.
