The temperature was rather low at the surface and dropped 

 less than 3° in the 100 meters; the salinity and hydrogen-ion 

 concentration were high and changed very little. Twelve 

 species were captured at the surface, 1 1 in the 50-meter tow, 

 and 23 in the 100-meter tow. Twenty-two species (70 per 

 cent) were each restricted to a single tow and only 4 were 

 found in all three tows. The single record for Oithona linearis 



and one of \ery few for Scolecithricella porrecta were found in 

 the 100-meter tow. This is one of the rare stations where 

 none of the three tows contained a single specimen of any 

 Corycaeus species. Again the Oncaea species were present at 

 the surface but were not so abundant as in the deeper tows. 

 Four of the 5 Oithona species were confined to the 100-meter 

 tow.
