The temperature diminished 1?5 in the 100 meters, the 

 salinity increased a trifle, and the hjdrogen-ion concentration 

 remained the same. Fourteen species were taken at the sur- 

 face, 31 in the 50-meter tow, and 38 in the 100-meter tow. 

 Thirty-three species (60 per cent) were each confined to a 

 single depth and 8 were found at all three depths. Corycaeus 



and Farranula were distributed at all three depths. Candacia, 

 Oithona, and Oncaea did not appear at all in the surface tow. 

 Paracalanus was evenly divided among the three tows, and 

 Pseudocalanus appeared only in the 100-meter tow. Both 

 the length and the volume of the three tows were practically 

 the same.
