It appears that when Ray was engaged in editing the work 

 of Willoughby, above referred to, he felt some doubt as regards 

 a fish which was called Orfus in Germany as to wliether it 

 miffht not be the same that in England was called Rudd or 

 Redeye; and when afterwards he published his synopsis this 

 doubt had become settled into a feeling of certainty. But this 

 doubt or mistake of the illustrious Ray was carried further by 

 Dr. Fleming; who not only represents the Rudd of Willoughby 

 and Ray as the Orfus of Germany, but also that this Rudd is 

 different from the species called the Redeye. The Orfus is 

 truly a distinct species, but it has not been recognised in 

 Britain, 



For the most part the Rudd frequents the same natural 

 districts as the Roach, where they are both found; and it is 

 suj)posed to have much the same habits. But it is worthy ol 

 notice, and not easily accounted for, that the former fish is 

 common in many pai'ts of Ireland, while the true Roach is 

 not known in that country, although supposed to be so because 

 the Rudd has usurped the name. They do indeed bear some 

 resemblance to each other; but the distinction of form between 

 them may be made with little difficulty; and, if closely ex- 

 amined there is little doubt that the characteristic habits and 

 appetites of each would also be found far from the same. 



The food of the Rudd is worms, molluscous creatures of 

 several kinds, and vegetables; but as it requires a good depth
