Again the temperature, salinity, and hydrogen-ion concen- 

 tration were high and did not change. Twenty species were 

 found in the surface tow and 48 in the SO-meter net. Thirt>'- 

 six species (70 per cent) were present in one tow and not in 

 the other, and 16 species were found in both tows. The 50- 

 meter tow was four and a half times as long as the surface 

 tow but had only twice the volume. The same genera as at 



station 81, together with many others, were confined to the 

 deeper tow, and the same genera were divided between the 

 two tows. Only a single specimen of Candacia was present 

 at the surface, all the others of the 4 species of this genus 

 appearing only in the SO-meter tow. Contrary to expectation, 

 the single specimen of Undeuchaeta was found at the surface 

 rather than in the deeper tow.
