It is only within a few years, I believe, that writers on 

 the Natural History of European Fishes have become aware 

 that in quoting, as was almost invariably the case, the figure 

 of the Syngnathus ophidion of Bloch, tab. 91, fig. 3, as the 

 true ophidion, they were not referring to, because that figure 

 does not represent, the true Syngnathus ophidion of Artedi 

 and Linnaeus. The fish, as represented by Bloch, does not 

 exhibit any appearance of a caudal fin, but if the species 

 there figured from be examined, it will be found to possess a 

 rudimentary caudal fin,* and could not therefore be con- 

 sidered as referred to by Linnaeus in the short but expressive 

 description, S. pinnis caudce ani pectoralibusque nullis, cor- 

 pore tereti.
