The temperature diminished, the saiinit>' increased, and 

 the hydrogen-ion concentration decreased in the 100 meters, 

 each but very little. Sixteen species were taken at the surface, 

 33 in the 50-meter tow, and 29 in the 100-meter tow. Twenty- 

 four species (54 per cent) were each confined to a single 



depth and 12 were present at all three depths. Corycaeus, 

 Farranula, and Oithona were well distributed at all three 

 depths. Candacia and Oncaea were confined to the two deeper 

 tows. These latter tows were a little longer than the one at 

 the surface and their volume was 50 per cent larger.
