Temperature high, diminishing only about 1° in the 100 

 meters; salinity moderate, increasing nearly- 1 point at the 

 100-meter depth; hydrogen-ion concentration fairl>" high, 

 changing scarcely at all. Eight species were found at the 

 surface, 39 in the 50-meter tow, and 46 in the 100-meter tow. 

 Thirty-six species (56 per cent) were confined to a single tow 

 and on!\' 3 were present in all three tows. Corycaeus and 



• Farranula were well distributed in depth and included the 3 

 species just mentioned, no other genus appearing at all the 

 depths. Candacia and Oncaea were most abundant in the 50- 

 meter tow, and Oithona in the 100-meter tow. The 100-meter 

 tow was 30 per cent longer than the suface tow and 10 per 

 cent longer than the 50-meter tow, but its proportionate 

 N'olume was considerably greater.
