892 CYPRINID.E. 



no difficulty in identifying it as the Cyprimm Buggenhagii 

 of Bloch ; and on tlie next visit to London of my friend 

 William Thompson, Esq. of Belfast, who has devoted such 

 unwearied attention to the Zoology of Ireland, I found that 

 he had also obtained an example of the same species of 

 Bream from the river Lagan, near Belfast, which circum- 

 stance was made public in the printed Proceedings of the 

 Zoological Society for 1837, page 56, as already quoted. 



Since the publication of the Supplement to the History of 

 British Fishes, in which this species was first mentioned as 

 a British Fish, the Rev. L. Jenyns has ascertained that it 

 exists also in Cambridgeshire ; an example, ten or twelve 

 inches long, having been caught in the piece of water which 

 ornaments his father's park at Bottisham. 



This species of Bream is at once distinguished from either 

 of the two species which have been hitherto found in this 

 country, by the greater thickness of its body, which is equal 

 to half its depth ; while in either of our other Bream the 

 thickness of the body is only equal to one-third of its depth ; 

 the scales of this species are also larger in proportion, although 

 the figure here given, not having been drawn on a comparative 

 scale with them, does not exhibit this peculiarity. The anal 

 fin is shorter and has a smaller number of rays than that of 

 Abramis blicca, which in its turn has its anal fin smaller, 

 and with fewer rays than that of Abramis vulgar is, which is 

 the Bream most generally known in this country. 



This new species was first described by Bloch from speci- 

 mens found in Swedish Pomerania, in the river Pene, and in 

 the lakes communicating with it. The specimens were sent 

 to Bloch by M. Buggenhagen, and hence the trivial name 

 which has been devoted to it for specific distinction. I have 

 also called it the Pomeranian Bream, considering it no ob- 

 jection to attach to this fish the name of the country in which 

 it was first discovered, although it may happen to have been
