COPEPODA. 



Ill the commencement of this paper it is mentioned that my 

 late friend Mr. Isaac C. Thompson recorded tliirty-one species 

 of Copepoda from Channel Island plankton. On the Harpac- 

 ticoida and fish-parasites nothing has been published, and the 

 few species in my own collection are not worth recording. It 

 is probable that many minute species \\q\n to our fauna will 

 hereafter be found in what may be expected to prove a 

 very ricji district. It is to be hoped that some naturalist 

 with good eyes and a steady hand will before long work at 

 these minims. But very much remains to be done in other 

 orders, especially among the Sympoda and Ostracoda.
