138 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 Bugrienhagii 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^ 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 4o, about 9 rows between it and 

 the dorsal ridge and o 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 anaf fins nearly transparent, or very slightly tinged with dusky, 

 chieflv towards their extremities ; caudal fin pale yellow. 



D. '11 ; P. 18 ; V. 1 4- 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 Pane, 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,! Leuciscus e7-i/throptIial}nns, 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. 



llutty noticed the " Roche " as frequent in the Liffey and Finglass 

 Brook ; and Templeton made the foUoAving 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 6i- inches, breadth 1 inch 10 lines. B. 4 ; D. 

 1|11, (reckoning 2 last from same base) ; P. 17 ; one V. 8, other 9 rays, yet 

 both apparently perfect; A. 1|12, reckoning 2 last from same base; 

 C. 19. 



2nd specimen. — Length 6f inches ; breadth 2 inches ; B. 4 ; D. 1|10 ; 

 P. 16; V. 9; A. 1|12; C. 19. 



3rd specimen. — Length 6^ inches; breadth 1 inch 10 lines; B. 4; D. 

 IjlO; P. 16; V. 9; A. IjiS; 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.
