The temperature was fairly high at tiie surface and fell 

 3?5 in the 100 meters, and the salinity diminished a little. 

 Sixteen species were taken at the surface, 27 in the 50-meter 

 tow, and 43 in the 100-meter tow. Thirty-fi\e species (60 

 per cent) were each confined to a single depth and 6 were 



present at all three depths. Corycaeus, Oithona, and Oncaea 

 were found in each of the tows, but Farranula and Candacia 

 were absent from the 50-meter tow. Labidocera detruncata, as 

 at the several preceding stations, was very abundant at the 

 surface.
