The surface temperature was low and fell more than 9° 

 in the 100 meters; the salinity and h>drogen-ion concentration 

 changed but little. Onl>- 4 species were taken at the surface, 

 24 in the 50-meter tow, and 18 in the 100-meter tow. Twenty- 

 three species (70 per cent) were each confined to a single tow 



tows. Corycaeus, reduced to a single species, and Oithona and 

 Oncaea with 3 species each, did not appear in the surface tow. 

 Candida simplex was here confined to the 100-meter tow, 

 though usually found nearer the surface. The 50-meter tow 

 was slightly shorter than either of the others but had the 



and only 1 {Paracalanus parvus) was present in all three largest volume.
