LISTS OF SPECIES BY STATIONS 



tow contains one of the two records of Monstrilla inscrta for 

 the entire cruise, 2 females. Two young males of a Pontella 

 species (probably lobiancoi), whose fifth legs were not fully 

 developed, were captured in the surface tow. Again the small 



127 



number of both species and specimens (except those of Far- 

 ranida) found at the surface indicates that a strong down- 

 ward migration of the copepods had been in progress before 

 the towing.

The moderate surface temperature fell 6° in the 100 

 meters, the salinity and hydrogen-ion concentration remain- 

 ing practically the same. There were 14 species in the surface 

 tow, 32 in the 50-meter tow, and ii in the 100-meter tow. 

 Thirty-three species (60 per cent) were each confined to a 

 single depth and 6 were present at all three depths. Corycaeus, 



Oithona. and Oncaea were distributed at all three depths, but 

 the 3 Farranida species were confined to the surface tow. 

 Candacia and Sapphirina appeared only in the 50-meter tow. 

 Fifteen specimens of Pandarus satyrus. including both sexes, 

 were taken from a shark captured at the surface and con- 

 stitute the onl\- record for this parasitic copepod.
