OF THE FIRTH OF FORTH. 61 



II. EURYSTOM^: 



BEROIDJE. 

 Idyia ovata (Less.). 



Firth of Forth (F. E. S.}. 



We have obtained this form in the autumn, 



off Elie. It is the Beroe ovata of Esch- 



scholtz. 



ACALEPHA. 



Aurelia aurita (Linn.). 



Very common in the autumn months ; 



often stranded on the beach. 

 Cyanea capillata (Eschsch.). 



Common in all the lower reaches of the 



Firth, in the autumn. 



ZOANTHAKIA. 

 I. ACTINAKIA 



SAGARTIAM. 



Adinoloba diantJius (Ellis). 



Firth of Forth, on rocks uncovered only 

 at very low tides (T. S. W.); Firth of 

 Forth (Colds.) ; Firth of Forth (MR). 



Sagartia troglodytes (Johnst). 



Firth of Forth (T. S. W.) ; Firth of Forth 

 (M'R). 



This species is commonly found on the 

 shore at very low water. We have obtained 

 it at Elie, Aberdour, and elsewhere. 

 The variety prasina of Gosse, found by 

 Dr Strethill Wright in the Forth, is an 

 inhabitant of deeper water. We have 

 dredged a considerable number of speci- 

 mens of it in the neighbourhood of Inch- 

 colm in 10 to 18 fathoms. It is charac- 

 terised by having the disc and tentacles 

 of a bright green colour.
