The temperature dropped only 4° in the 100 meters; the 

 salinity and hydrogen-ion concentration remained almost 

 constant. Fourteen species were taken at the surface, 53 in 

 the 50-meter tow, and 3i in the 100-meter tow. Forty-seven 

 species (66 per cent) were each confined to a single tow and 

 6 were found in ail three tows. Corycaeus, Farranula, Oithona, 



and Oncaea were for the most part in the 50-meter tow, and 

 Oncaea did not appear at all in the surface tow. The 100- 

 meter tow contains one of the two records for Centropages 

 hamatus in the Pacific; since in the other record, station 55, 

 it was found at the surface, very little can be told about its 

 reaction to light.
