This was the only occasion during the entire cruise when 

 tows at all three depths were taken between stations. The 

 vertical distribution of the species was 31 at the surface, 33 

 at 50 meters, and 32 at 100 meters, an exceptionally uniform 

 dispersion. Twenty -one species (43 per cent) were confined to 

 a single depth, and 19 were found at all three depths. This is 



the only cruise record for Sapphirina darwinii, and the only 

 Atlantic record for Eucalanus attenuatus. Megacalanus prin- 

 ceps, and Pachos punctaium. The presence of these isolated 

 species and the unusual uniformity in vertical distribution is 

 accounted for by the fact that these tows were taken during 

 the night and not in the daytime.

At this station only a surface tow was taken, with the 

 temperature 20?5. the salinity 36.4 o/oo, and the hydrogen-ion 

 concentration 8.23. The time was late in the forenoon and the 

 sea was too rough to attempt the deeper tows. It must ha\e 



been also very dark and lowering, since the 2 Rhincalanus 

 species were still at the surface, whereas they were usually 

 confined to the deeper tows. This was the only record for 

 Centropages chierchiae during the entire cruise.
