The temperature was high and diminished nearly 1°; the 

 salinity increased half a point, and the hydrogen-ion concen- 

 tration remained practically the same. Fifty-three species 

 were taken in the 50-meter tow and 54 in the 100-meter 

 tow, an exceptionally even depth distribution. Fort>-one 



species (55 per cent) were present in one tow and absent 

 from the other, and 33 were found in both tows. The 100- 

 meter tow contains one of the few records for Amallothrix 

 propinqua. Candacia, Corycaeus, Farranula, Oithona, and 

 Oncaea were each well di\ided between the two tows.

This surface tow yielded 16 species, but most of the tow was made up of development stages of Candacia simplex.
