This is the second group of three nocturnal tows all taken 

 on the same da\', two in the early morning, and one in the 

 late evening. The three yielded 44 species, 32 in A, 17 in B, and 

 22 in C. Twenty-six species (60 per cent) were each confined 

 to a single tow and 9 were present in all three tows. Here also 



we find Megacalanus and Undeuchaeta coming up from below, 

 and Corycaeus and Oncaea present in tows A and C, but almost 

 lacking in B. One specimen of Oithona was found in B, but 

 none in A or C. Except for the 1000-meter tow at station 

 64, tow C contained the only record for Euchaetn spinosa.
