Almost the whole of what we knoAv of this fish is contained 

 in a communication by W. Thompson, Esq., of Belfast, to the 

 Zoological Society, with a figure, which we have copied.; and. 

 the comm.nnication is transferred to the fourth volume of the 

 "Natural History of Ireland" by the same gentleman: to 

 which we add, that an example of the same species has 

 been since caught, or rather found, thrown on the shore by 

 a storm, in the harbour of Valencia, in Ireland; and several 

 others of small size were found by Mr. Edwards at T3anfF, of 

 which we shall give an account. Mr. Thompson remarks that 

 in external characters it is excluded from the OpJiia by not 

 having barbies; and although it agrees with the genus Fierasfer 

 in being without these appendages, yet by having the dorsal 

 fin elevated and strongly developed, it does not range with 

 them; to which I add, that this character is excluded fron^ 

 our definition as above, since it might seem like a contradiction 

 to classify under such a character the only British fish of 

 the genus, and which cannot be so described 'J'he author 

 further says — in Cuvicr's Animal Kingdom the Ophidium
