REMARKS.. tne temperature was moderate at the surface and dropped five and 
a half degrees in 100 meters ; the salinity and hydrogen ion were fairly 
high and constant« Thirteen species were taken at tne surface, twenty- 
one in the 50-meter and thirty-one in the 100-meter tow. Twenty seven spe— 
cies: (64%) were each confined to a single tow and eight were present in ail 
three towse Corycaeus, Farranula, and Oithnona were well represented in 
species,.and although there were only two species of Oncaea they were both 
abundant in the two deeper towse The four specimens of Metridia lucens 
in the 50-meter tow was the largest number of the species taken at any sta- 
tion in the eastern Pacifice Mecynocera, which was represented by a 
Single specimen in the four preceding surface tows,is here common in the 
50-meter tow and abundant in the 100~meter tow. Heterorhnabdus, the three 
Neocalanus species and Pleuromamma appear only in the 100~-meter towe
