Zoological Society, with a figure, which we have copied; and 
the communication 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 Banff, of 
which we shall give an account. Mr. Thompson remarks that 
in external characters it is excluded from the Ophia 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 cxcltuled fiotn 
our definition as above, since it might seem like a contradiction 
to classify under such a character the only Briiisli fish of 
the genus, and which cannot be so descriljed. The author 
further says — in Cuvier’s Animal Kingdom the Ophidium
