Volume of tow, 36 cm'; time, 12''10'° to 2'>16'" a.m.; surface 

 only. Twenty-one of the 40 species here taken at the surface 

 were confined to the 50-meter and 100-meter levels at stations 

 49 and 50. Several others that were taken in the surface tow 



at one or the other of those two regular stations are here found 

 in greater numbers. We are thus furnished with good evidence 

 of the nocturnal migration to the surface of considerably 

 more than half of the species here listed.
