AND AT SEATON SLUICE, NOETHTTMBERIAND. 2^ 



* British Copepoda ' it is recorded from only one locality — the 

 mouth of the Seaton Burn, Northumberland. It may be of 

 interest to enumerate some of the Copepoda that have been 

 found associated together in the upper reaches of the Perth 

 Estuary, as Eurytemora affinis, Poppe ; Tachidius crassicornis, 

 Scott ;* Delavalia palustris, Brady ; Thalestris harpactoides, 

 Clans ; Platychelipus Uttoralis, Brady ; Hersiliodes Uttoralis, 

 Scott ; Acartia longiremis, Lilljeborg ; Temora longicornis, 

 Miiller, etc." And still more recently f Mr. Scott has pub- 

 lished a very similar list of Copepoda obtained from brackish 

 pools near the head of "West Loch Tarbert, Argyleshire. This 

 list includes Cyclops cequoreus, Fischer (also obtained at Seaton 

 Sluice) ; Tachidius Uttoralis, Poppe ; Delavalia palustris, Gr. S. 

 Brady ; Canthocamptus palustris, Gr. S. Brady ; Cletodes tenui- 

 cornis, Scott ; Platychelipus Uttoralis, G. S. Brady. The general 

 correspondence of this list with those of the Solway and Seaton 

 Sluice as well as with those given by Mr. I. C. Thompson for 

 similar situations in Lancashire and !N'orth "Wales is quite 

 remarkable. 



Amongst the Copepoda found in the Seaton Sluice pools was 

 one — Nannopus palustris, which I was unable from want of 

 sufficient material to describe or figure very fully. This 

 species does not seem to have been noticed by any other 

 British naturalist except by Mr. T. Scott, who took it in 1891 

 '* at the mouth of the Cocklemill Burn near Largo, Pirth of 

 Perth," but M. Eugene Canu has recently found it in the 

 Estuary of Wimereux, Pas de Calais, and in his admirable 

 memoir on the Copepoda J of that region, has given a completely 

 illustrated account of it. M. Canu states that the animal was 

 found where the common green seaweed Enteromorpha intesti- 

 nalis was growing abundantly, and that in company with it 

 were Gohius minutus and the two shrimp-like Crustacea P'ala- 

 monetes varians and Mysis vulgaris. These are strictly brackish-
