The temperature and hydrogen-ion concentration dimin- 

 ished a little at the 100-meter depth, and the salinity in- 

 creased. There were 24 species in the 50-meter tow and 25 

 in the 100-meter tow. Twenty-five species (70 per cent) each 



appeared at a single depth and 12 at both depths. Corycaeus 

 and Oncaea were more numerous in the 50-meter tow; Farran- 

 ula did not appear in either tow. Probably Farranula would 

 have been present in the lost surface tow as at station 110.
