The temperature, salinity, and hydrogen-ion concentration 

 were all high at the surface; the first fell 9° in the 100 meters 

 and the other two diminished a little. Twenty-two species 

 were taken at the surface, 25 in the SO-meter tow, and 33 in 

 the lOO-meter tow. Thirty-two species (61 per cent) were 

 restricted to a single tow and 8 were found in all three tows. 

 The Eucalanus species were again conspicuous in the two 



deeper tows, but only a single specimen was found at the 

 surface. Five specimens of the new Onchocalanus species were 

 taken in the 50-meter tow, and 5 of the new genus Danodes 

 at the surface. The Corycaeus and Oncaea species were well 

 distributed in all three tows. Haloptilus, Lubbockia, and 

 Lucicutia were all restricted to the lOO-meter tow, which 

 contains one of two records of Lucicutia curta for the cruise.
