MALACOPTERYGII. 
Bloch. Part 3, tab. 95. On inspecting the produce of a fishing rod at 
the river Lagan, near Belfast, on the 6th of May, 1836, 1 detected a bream 
differing from the common species, and secured it for examination. It 
agreed so fully with Bloch’s description of the Cyprinus Buggenhagii as 
to satisfy me of its identity, the only difference consisting in the number 
of rays in the pectoral fin, 12 being enumerated by him, and 18 appearing 
in the specimen ; several of them, however, being very short, may have 
escaped Bloch’s notice. 
The description drawn up from my specimen the day it was procured 
is as follows : — Length, 5-±- inches ; depth, 1-i- inch ; head one-fourth of 
the entire length ; diameter of the eye equal to one-fourth of the length of 
the head ; scales on the lateral line about 45, about 9 rows between it and 
the dorsal ridge and 5 rows below it ; under point of the caudal fin 
longer than the upper. Colour of the sides silvery, ‘tinged with blue 
towards the back ; irides very pale yellow ; the dorsal, pectoral, ventral, 
and anal fins nearly transparent, or very slightly tinged with dusky, 
chiefly towards their extremities ; caudal fin pale yellow. 
D. 11 ; P. 18 ; Y. 1 -\- 9 ; A. 20 (first extremely short); C. 18. 
This species, which is new to Britain, is stated by Bloch to be found 
in Swedish Pomerania, in the river Pene, and in the lakes communicating 
with it.* 
More attention to our fishes will probably show that this species is not 
confined to the one river. 
The Rudd or Red-eye, f Leuciscus erythropthalmus, Cuv., 
Is found from North to South of the island, — chiefly in lakes and slow 
rivers. It is probably found in every County possessing suitable localities. 
Rutty noticed the “Roche” as frequent in the Liffey and Finglass 
Brook ; and Templeton made the following note in reference to the rudd : 
■ — “ Exceedingly common in the North of Ireland, where it is mistaken 
for the roach.” 
Three specimens of the “ Red Roach ” of L. Neagh which I examined 
in March, 1835, were as follows : — 
1st specimen. — Length 6^- inches, breadth 1 inch 10 lines. B. 4 ; D. 
1 1 1 1, (reckoning 2 last from same base) ; P. 17 ; one V. 8, other 9 rays, yet 
both apparently perfect; A. 1 1 12, reckoning 2 last from same base; 
C. 19. 
2nd specimen. — Length 6f inches ; breadth 2 inches ; B. 4; D. 1 1 10 ; 
P. 16; Y. 9; A. 1 1 12 ; C. 19. 
3rd specimen. — Length 6^ inches ; breadth 1 inch 10 lines ; B. 4 ; D. 
1 1 10 ; P. 16; Y. 9; A. 1 j 13 ; C. 19. Irides silvery tinged with pale 
orange, pupil black. Lateral line as in Donovan’s pi. 40. Colour , “ back 
dusky green, sides and belly silvery.” P. and D. fins dusky, the latter 
faintly clouded with dull red towards the extremity ; the greater portion 
(towards extremity) of V., A., and C. fins bright scarlet. 
The Minnow, Leuciscus Phoxinus , Cuv., 
Is found in several localities within the Counties of Dublin and Wicklow, 
to which it is believed by some persons to have been introduced.
