The temperature was high at the surface and dropped 3° 

 in the 100 meters; the salinity increased and the hydrogen- 

 ion concentration diminished slightly. Seventeen species 

 were taken at the surface, 35 in the 50-meter tow, and 47 

 in the 100-meter tow. Thirty-seven species (58 per cent) 



were each confined to a single depth and 8 were present at 

 all three depths. The fi\'e genera Candacia, Corycaeus, Farran- 

 ula, Oithona, and Oncaea were each present in all three tows, 

 but Oncaea was particularly abundant in the 100-meter 

 tow.
