REMARKS.. The temperature, salinity and hydrogen ion were all high at the 
surface, the former fell nine degrees in the 1€9 meters and the two latter 
diminished a little. Twenty-two species were taken at the Surface, twentv- 
five in the 50-meter tow and thirty-three in the 1l00—meter towe Thirty- 
two species (61%) were restricted to a single tow and eight species were 
found in all three tows-« The Eucalanus species ‘Maa again conspicuous in 
the two deeper tows, but only a single specimen was found at the surface.. 
Five specimens of the new genus Pachosina were taken in the 50 meter tow » 
and five of the new genus Danodes at the surface. The coryeaeus and Oncaea 
species were well distributed in all three tows- Haloptilus,, Lubbockia 
were, 
and Lucicutia aeg all restricted to the 100-meter tow and this contains the 
bia Curta for the entire cruise.
