The temperature was high at the surface and dropped 7?S 

 in the 100 meters; the salinity and hydrogen-ion concentra- 

 tion both diminished slightly. Sixteen species were found at 

 the surface, 26 in the 50-meter tow, and 47 in the 100-meter 

 tow. Thirty-six species (62 per cent) were each confined to a 

 single tow and 8 were present in all three tows. Farranula 



was found at all three depths, but onlj- a single species each 

 of Corycaeus and Oncaea and none of Oithona was present 

 in the surface tow. Labidocera detruncata was especially 

 abundant at the surface, adults as well as many development 

 stages. The presence of this species in all three tows is worthy 

 of note as it is usually confined to the surface.
