On August 24th collections of the open sea and 

 inshore plankton were again taken. The open sea 

 sample was collected three miles West of Bradda Head, 

 and the shore one off Flesh wick. The latter place is 

 about five miles due East from the former.

The most noteworthy difference between these two 

 samples is in the quantity taken. The plankton inshore 

 was evidently more abundant than in the open sea. There 

 was also a slight change in the variety of organisms 

 captured at the two places. Copepoda were just as 

 numerous at the one station as at the other. Anomalocera 

 and I J arajjo?itella were noted in the open sea but not 

 inshore, while Pseudocalanus and Temora were found 

 inshore only.
