This nocturnal surface tow was less productive than those 

 between stations 35 and 36, and yielded only 19 species, half 

 of which were represented b>' 3 specimens or less. Calanus 

 propinqiius was not present at station 41 and only in the 100- 



meter tow at station 42. Two of the Corycaeus species, agilis 

 and lypicus, were confined to the deeper tows at stations 41 

 and 42, and catus did not appear at either of those stations; 

 nor did Miracia efferata and Undinula vulgaris.
