The body long and tapering; vent placed near the throat. Gill 

 openings wide, the gill membranes united below: particularly dis- 

 tinguished from Oj)hidium by the absence of barbies. An apodal

 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. IMr. Thompson remarks that 

 in external characters it is excluded from the Opliia 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 from 

 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. The author 

 further says — in Cuvier's Animal Kingdom the OpJtidium
