The temperature, salinity, and Indrogen-ion concentration 

 were high and the first two were exactly and the last prac- 

 tically the same at both depths. Seventeen species were 

 found at the surface and 44 in the 50-meter tow. Forty-five 

 species (85 per cent) were present in one tow but not in the 



other; 8 species were found in both tows. Corycaeus and 

 Oithona were much more abundant in the deeper tow; Far- 

 ranula constituted a large percentage of the surface tow. 

 Although the 50-meter tow was a little shorter than the 

 surface tow, its volume was nearly three times as large.
