The temperature was high at the surface and fell 16° in 

 the 100 meters; the salinity increased and the hydrogen-ion 

 concentration decreased somewhat. Twenty-one species 

 were taken at the surface, 38 in the SO-meter tow, and 56 

 in the 100-meter tow. Fifty-four species (66 per cent) were 

 each confined to a single depth and 5 were present at all 

 three depths. The three tows were of exactly the same 



length, but the volume of the 100-meter tow was two and a 

 half times as large as that of either of the others. Corycaeus 

 and Oncaea were present in each of the tows, but neither did 

 Farranula appear in the 50-meter tow nor Oithona in the 

 surface tow. The 100-meter tow contained Temoropia 

 mayumbaensis, which was found also at station 35 in the 

 eastern Pacific.
