The moderate surface temperature fell 3?5 in 100 meters, 

 the salinity and hydrogen-ion concentration remaining nearly 

 constant. There were 41 species in the surface tow-, 57 in the 

 50-meter tow, and 41 in the 100-meter tow. Forty-two species 

 (50 per cent) were each confined to a single tow and 15 were 



present in all three tows. Corycaeus, Farranula. and Oncaea 

 were well distributed in all three tows, but Oithona did not 

 appear in the surface tow and Candacia was confined to the 

 50-meter tow with one exception. The 50-meter tow contains 

 the second of two records for Monstrilla inserta, 5 females.
