REMARKS .. The surface tow is lackirg, the other two showed high temperatures, 
salinity and hydrogen ion, with little variatione Twenty-six species 
were taken in the 50-meter tow and twenty-eight in the 100-meter tow- 
Twenty-eight species (70%) were found in one tow and not in the ot ther, while 
ten were present in both towse. The 50 meter tow contains one of the two 
Paciric records for two species y Corycaeus minimus and Temcra longicornis,,. 
and also has two other rare species Steleatkrieella, propingua and Euchirella 
messinetisis. Of the four genera rated as very abundant at the surface in the 
record of Station 77 only two appear here as abundant in the 50-meter towe 
Conversely Rnincalanus,. of which there was but a single specimen there at the 
surface, is here abundant in both the deeper tows.. Farranula, Oncaea, and 
Mecynocera are also especially abundant in the 50 meter tow, and Oithona in 
the 100-meter tow.
