The temperature and hydrogen-ion concentration were 

 high, the salinity a little lower, but all three remained about 

 the same at the two depths. Nineteen species were found at 

 the surface and 49 in the 50-meter tow. Forty-four species 

 (80 per cent) were confined to one of the two tows and 12 



were found in both tows. Corycaeus and Oithona were more 

 abundant in the deeper tow, the latter not appearing at all 

 at the surface. Farranula and Oncaea were about evenly 

 divided between the two tows. Only one Candacia {simplex) 

 appeared at the surface, the others only in the SO-meter net.

Every one of the IS species obtained in this surface tow 

 was as distinctly pelagic as those captured in the open ocean. 

 The littoral copepods of these oceanic islands do not seem to 

 venture very far into the surrounding ocean. On the contrary. 



the pelagic copepods come in \ery close to the shore, cspecialh' 

 at the surface. Undinula and Calanopia made up about 90 

 per cent of this tow, each of the other genera being confined 

 to a few specimens.
