The temperature was high at the surface and fell only 

 0?5 in the 100 meters; the salinity and hydrogen-ion con- 

 centration also changed but little. Twenty-one species were 

 captured at the surface, 37 in the 50-meter tow, and 29 in 

 the 100-meter tow. Twenty-eight species (52 per cent) were 

 each confined to a single depth and 7 were present at all 



three depths. Corycaeus, Farranula, Oithona, and Oncaea 

 were found in each of the tows, and especially at the surface, 

 but Candacia did not appear in the surface tow. This latter 

 tow contains one of the few records (or Anomalocera patersonii 

 during the cruise. The 50-meter tow contains the first record 

 of the new species Scolecithricella spinacantha (cf. sta. 159).
