N.D. 

 CvTHF.RF. albomaculata Baird. 



Common between tidemarks, and recorded by G. S. B. from 

 a freshwater lake at Bolam, Northumberland. 



The Bolam habitat must be looked upon as doubtful ; a 

 renewed search there has resulted in failure to find the species, 

 and it is possible that it found its way accidentally into the 

 earlier gathering. N.D. 



Cythere Robertsoni G. S. Brady. 



Budle Bay, Northumberland ; Sunderland, tidemarks, and 



in several places off the Durham coast in 29-55 fathoms 



(G. S. B.); Seaton Sluice (A. M. N.) N.D. 



Cythere limicola (Norman). 



1866. Cythereis limicola, Norman, Nat. Hist. Trans. North- 

 umberland and Durham, vol. i., p. 20, pi. vi., figs. 1-4. 

 Confined to the coralline zone, but not rare at such a depth 

 off the coast. N.D. 



Cythere cuneiformis G. S. Brady. 



More generally found in 15-40 fathoms, but also occurs in 

 several estuarine localities in Northumberland, and has been 

 found between tidemarks on mud-covered rocks at Whitley 

 (G. S. B.) ; Seaton Delaval (A. M. N.) N.D. 



Cythere navicula (Norman). 



Budle Bay, Northumberland (G. S. B.) N. 



Cythere villosa (G. O. Sars). 



Among small weeds between tidemarks in estuaries, and 

 more rarely dredged. 



The specimens referred to C. borealis Brady taken at Seaton 

 Carew, belong really to C. villosa. N.D.
