Again the temperature, salinit>", and h)-drogen-ion con- 

 centration were high and almost the same for both depths. 

 Only 5 species were found at the surface, and 34 in the 50- 

 meter tow. Thirty-one species (90 per cent) appeared in one 



tow and not in the other, and only 4 were common to both. 

 The surface tow j'ielded but 4 specimens besides the 2 species 

 of Farranula. The 50-meter tow contained a single female of 

 Sapphirina pyrosomatis, found in only two other localities.

The temperature, salinity, and hydrogen-ion concentration 

 were high and changed but little at the two depths. Eight 

 species were found at the surface and 31 in the SO-meter tow. 

 Twenty-seven species (89 per cent) were found at one depth 



onh- and 6 at both depths. In the surface tow Farratiiila cari- 

 nata exceeded in abundance all the other species combined, 

 and in the 50-meter tow Pseudocalanus minutus was the 

 most abundant single species.
