THE COPEPODA OF LIVERPOOL BAY. 67 
Euterpe gracilis, Claus. 
Several specimens of this rare form have been taken 
about Puffin Island during the past summer. Brady, in 
his “‘Monograph of British Copepoda’ (Ray Society, 
1876—1879), states there have been previously only two 
known habitats for this species, viz. Heligoland, and 
Kinsale harbour, Ireland. I recently found it about the 
Canary Islands. 
Dactylopus tisboides, Claus. 
D. stromu, Baird. 
Diosaccus tenwicornis, Claus. 
These three species have been sparingly found by Mr. 
W.S. McMillan and myself in the peaty pools about the 
submarine forest, Leasowe. 
Thalestris clausw, Norman. 
T. rufoconcta, Norman. 
T. hibernica, Brady and Robertson. 
T. longimana, Claus. 
These four species of Thalestris I have found at various 
times in the rock pools about Hilbre Island. 
Westwoodia nobilis, Baird. 
Rock pools at Hilbre Island. 
Harpacticus fulvus, Fischer. 
Rock pools at Puffin Island, also about Hilbre Island. 
‘Peltidium interruptum, Goodsir. 
Rock pools at Hilbre Island and by tow-net off Anglesey, 
and frequently around Puffin Island. 
Idya furcata, Baird. 
At Penmaenmaur, in open sea and in tidal pools.
