The temperature, salinity, and h>drogen-ion concentration 

 were high and changed very little in the 100 meters. Twenty- 

 nine species were found at the surface, 51 in the 50-meter 

 tow, and 45 in the 100-meter tow. Thirty-six species (49 per 

 cent) were each confined to a single tow and 13 were present 

 in all three tows. Corycaeus, Farranula, and Oncaea were 

 divided among the three tows, but Eucalanus, Euchirella, 



Oithona, and Undinula were found only in the two deeper 

 tows. The surface tow contained one of the two records for 

 Sapphirina ovatolanceolata; the other 4 species of Sapphirina 

 were found, with one exception, in the two higher tows. The 

 two deeper tows were each 20 per cent longer than the sur- 

 face tow; the volume of the 50-meter tow was 10 per cent 

 larger, but that of the 100-meter tow was 150 per cent larger.
