These are the last three of the nocturnal tows and were 

 all taken the same night between midnight and morning. 

 The three tows total 37 species: 20 in tow A, 29 in tow B, and 

 9 in tow C. Twenty-two species (60 per cent) were each con- 

 fined to one tow and 6 were found in all three tows. Corycaeus 

 is here reduced to a total of 3 specimens, and Farranula and 



Oncaea are entirely absent from tow C, which was the latest 

 of the three, in the early morning. Megacalanus was present 

 in two of the tows, the earliest and the latest, but Undeuchaela 

 did not appear in any of them. Candacia, Farranula, and 

 Oncaea were practically restricted to tow B, from 2'' to 4'" a.m. 

 on January' 3, 1929.
