REMARKS. We have here high temperature, salinity and hydrogen ion in both 
tows, with practically no variation. Thirty-one species were taken at the 
surface and forty-three in the 50-—meter towe Thirty-four species (63%) 
were present in one tow but wholly absent from the other and twenty species 
were taken ir both tows» The three Eucalanus species, the two Eucnirella 
species and Rhnincalanus did not appear at the surface while the Candacia, 
Corycaeus, Farranula and Oncaea species were about equally divided between 
the two towse The 50-meter tow was two and a half times the length of 
the surface tow and its volume was one and a half times as greate Eucala- 
nus, Euchirella, Haloptilus and Rhincalanus appeared only in the deeper tow 
Labi docera Undinula ee ; 
while Gesyemets and Smeaea were well divided between the two tows.
