The drop in temperature here was 40 per cent, the rise in 

 salinity 2 points, and the rise in density 5 points. The 50- 

 meter tow, with a length three times that of the surface tow, 

 had a volume only one-half larger, and yielded half as many 

 more species. The 100-meter tow had twice the volume of the 

 50-meter tow, with the same length, and yielded almost twice 

 as many species. There were 25 species at the surface, 40 in 

 the SO-meter tow, and 72 in the 100-meter tow. Forty-six 



species (53 per cent) were each confined to a single tow and 

 11 were present in all three tows. The 1 Aetideus and 2 

 Euaetideus species were restricted to the 100-meter tow; the 

 3 Candacia species, 4 of the 5 Eucalanus species, the 4 Oithona 

 species, and the 2 Rhincalanus species appeared only in the 

 two deeper tows. Corycaeus and Oncaea were well represented 

 with species which were divided among all three tows. One 

 specimen of the new genus Danodes was taken at the surface.
