Again the temperature, salinity, and hydrogen-ion concen- 

 tration were high at the surface; the temperature decreased 

 5° and the other two diminished only slightly in the 100 

 meters. Twelve species were found at the surface, 33 in the 

 50-meter tow, and 38 in the 100-meter tow. Thirty-one 

 species (55 per cent) were each confined to a single tow and 

 only 3 were present in all three tows. Five specimens of the 

 new Onchocalanus species were here taken at the surface and 



none in the deeper tows. The 4 species of Eucalanus were 

 again found in both the deeper tows but not at the surface. 

 Corycaeus and Oncaea were distributed in all three tows, with 

 the latter much more abundant in the two deeper tows. Canda- 

 cia, Haloptilus, Heterorhabdus, and Lucicutia did not appear 

 at the surface, and, contrary to the usual distribution, the 

 same is true for Farranula and Oithona. Temora was very 

 abundant at 50 meters and less so at 100 meters.
