REMARKS.. These two surface tows were made the same nignt five or six miles 
apart. Together they yielded fifty species of which 44 were found in one 
tow and 25 in the othere Thirty-two species (64%) were taken in one tow 
only and did not appear in the other,while eighteen species ( 36% ) were pres-— 
ent in both tows... Here again is a striking diversity in the surface distri- 
bution of the copepods within a comparatively short distances And since 
these tows were nocturnal and some of the species at least had come to the 
surface from below it indicates that the diverse distribution was not con- 
fined to surface species alone.. The three small genera, Corycaeus, Farranula
