REMARKS.. These two surface tows were taken on successive nights at about 
the same time and only a mile aparte One yielded twenty-eight species 
and the other thirty species« Fourteen species (40%) were each confined 
to one of the tows and did not avpear in the other, while twenty-two species 
(60%) were present in both tows.. This is a much more equable distribution 
than that of the tows taken between stations 60 and 6le It is worthy of 
note that altho one tow covered a distance five and a half times freater than 
the other there is very little difference in the volume , and that littie is 
in favor of the shorter tow. 
The second tow contains one of two records of Pontella atlantica in the 
eastern Pacific. Both tows were taken near midnight and in both five of the 
six species of Oncaea appear in varied abundance, while the sixth species 
Was absent from the later towe
