The temperature dropped 1° in the 100 meters, the salinity 

 increased slightly, and the hydrogen-ion concentration re- 

 mained virtually the same. Eighteen species were taken at 

 the surface, 26 in the SO-meter tow, and 33 in the 100-meter 

 tow. Twenty species (43 per cent) were each confined to a 



single depth and 1 1 were present at all three depths. Corycaeus 

 and Farranula were found in all three tows, Oilhona and Can- 

 dacia in the lower tows, and the single species of Euchaeta and 

 Oncaea in the two upper tows. The surface tow was twice as 

 long as the 50-meter tow, but its volume was smaller.
