A high temperature at the surface and at SO meters, with a 

 drop of more than 5° at 100 meters; the saiinit>' and hydrogen- 

 ion concentration \-arying \'ery little. Twenty-nine species 

 were found at the surface, 24 at 50 meters, and 34 at 100 

 meters. Thirteen species were found at all three depths, and 



34 (63 per cent) were each present in but one tow. The surface 

 tow contained the only Atlantic record of Calanopia elliptica, 

 and the SO-meter tow the only Atlantic record of Corycaeus 

 furcifer. Corycaeus, Farranula, and Oncaea were each well 

 represented in the surface tow, with only one Oithona species.
