The temperature, salirtity, and h\drogen-ion concentration 

 were high and practically the same at the two depths. Ten 

 species were taken at the surface and 22 in the 50-meter net. 

 Twent>-two species (80 per cent) were present in one tow 



and not in the other, and 5 were found in both tows. Corycaeus 

 and Farranula were well di\ ided between the two tows; 

 Oithona and Oncaea were both found only in the 50-meter 

 tow.
