*Anchorage, Hanga Roa, Easter Island. 



These two surface tows were taken late in the afternoon and 

 early evening (4'' 50"" to 6'' 40" and 6'' 50™ to 9'" p.m.) at the 

 anchorage ofif Easter Island. Although the water here was 

 comparatively shallow and the anchorage was near the shore 

 of the island, the only really littoral species appearing in the 



catch was Metis jousseaumei. This is probably because of the 

 fact that the towing was in an open roadstead and not in a 

 landlocked harbor. None of the other surface tows from this 

 anchorage yielded a single littoral species, only the pelagic 

 forms that were common in the ocean around the island.

*Anchorage, Hanga Roa, Easter Island. 



Four tows, surface onh'. The time of these tows was not 

 recorded, but all four were on the same date. Like the two 

 preceding tows, they were all in shallow water near the an- 

 chorage; they did not yield any littoral species. Eleven of the 



species here recorded were not obtained in the two previous 

 tows, and 19 present in those two tows do not appear here. 

 Calanus minor and the 2 Pontella species, all 3 pelagic, are 

 the most noteworthy additions in these four tows.

Two afternoon surface tows taken two days later than the 

 previous ones and 2 miles northeast of Easter Island, where 

 the water must have been considerably deeper. Many of the 

 species captured nearer the island do not appear in these two 



tows. E\'identK' there is a great diversit\' in the surface dis- 

 tribution of the copepods even within the narrow limits 

 co\ered by these eight tows. The most noticeable difference 

 here is the entire absence of Oithona and Oncaea.
