On comparing with the Copepod record for 1907, we 
find that the numbers are not nearly so high for the first 
half of the present year. In 1907 the Copepoda rose to 
nearly 30,000 on April 27th and 15,000 in June, as 
compared with about 4,000 this year. Then again on 
October 14th, 1907, the record reached 27,000, while this 
year the only high record in autumn is 12,560 on 
October 6th. 
We have taken out for separate treatment the six 
more important species of Copepoda (viz., Calanus 
helgolandicus, Pseudocalanus elongatus, Acartia clausi, 
Oithona similis, Temora longicornis, and  Paracalanus 
parvus) with the results shown in the following list : —
