The temperature dropped 44 per cent in the upper 100 

 meters; the salinity rose 3 points and the density 6 points. 

 Forty-nine species were taken at the surface, 42 in the 50- 

 meter tow, and 55 in the 100-meter tow, but the volume of 

 the surface tow was seven times that of the 50-meter tow and 

 three and a half times that of the 100-meter tow although its 

 length was 20 per cent less than that of either of the others. 

 Forty-four species (50 per cent) were each confined to a 



single tow, and 15 were found in all three tows. The 3 speci- 

 mens of Oithona vivida taken in the two deeper tows are the 

 only ones obtained during the cruise. Numerals are less fre- 

 quent in the abundance records, but there are still 6 species 

 each of which is represented by a single specimen. Corycaeus, 

 Oithona, and Oncaea were each well represented by species 

 in all three tows, and the surface tow contained 3 specimens 

 of the new genus Danodes.
