The temperature was moderate at the surface and fell 3° 

 at 50 meters and 2° more at 100 meters; the salinity and 

 hydrogen-ion concentration remained nearly constant. There 

 were 12 species in the surface tow, 22 in the 50-meter tow, 

 and 25 in the 100-meter tow. Nineteen species (53 per cent) 

 were each confined to a single tow and 6 were present in all 

 three tows. Corycaeus was confined to the two deeper tows. 



Farranula appeared only in the surface tow and was reduced 

 to a single species, Oithona and Oncaea were distributed in 

 all three tows; Candacia was confined to the 100-meter tow, 

 and this is the only record for the species tenuimana. In the 

 surface tow Paracalanus parvus was especially abundant and 

 constituted at least 90 per cent of the copepods. The 50-meter 

 and 100-meter tows were badly choked with diatoms. 



Between stations 115 and 116 

 June 30, 1929; 38° 22' N, 147° 20' E; 5 species 



Acartia danae 



Corycaeus sp., mutilated. 



Oithona similis 2 



Paracalanus parvus c 



This nocturnal surface tow yielded only 5 species and is 

 unworth\' of comment except that e\ery specimen was badly 



parasitized by a fungus. The length of the tow was 0.1 mile 

 and the \olume 32 cm'.
