38 FISHES AND FISHERIES OF THE IRISH SEA. 
Clyde, Moray Firth, Firth of Forth, &c. ‘‘ Dr. Jacob obtained one 8 feet 3 inches long oft 
Dublin Bay, in the autumn of 1841, and which weighed fully 300 Ibs.” 
The long-finned Tunny (Orcynus germo) has much the same distribution as the present 
species, but has not been recorded for the Irish Sea area. 
THYNNUS PELAMYs (Linn.)—Bonito. 
(Day’s British Fishes, vol. I., p. 100, Pl. XXXVII.) 
The Bonito, like the Tunnies, is a southern and pelagic fish, and really has its home in 
the tropical Atlantic ; but occasional specimens reach our shores, and have been taken in the 
Firths of Forth and Clyde, at Plymouth, &c. Couch records an example found at Whitehaven, 
in Cumberland, and ‘‘in August, 1880, one, 2 feet long, which weighed 6? Ibs., was secured 
at Hawgill, Solway Firth” (Day). It has also been taken off the Isle of Man. 
ECHENEIS REMORA, Linn.—Remora. 
(Day’s British Fishes, vol. I., p. 108, Pl. XXXIX., Fig. 2.) 
This fish does not really belong to the British fauna, but has been occasionally brought 
into our seas by the larger fishes to which it is in the habit of attaching itself by its dorsal 
sucker. One of these records refers to our district, and is as follows :—‘* In July, 1848, one 
was captured at Clontarf, Dublin Bay, adhering to the gills of a blue shark Carcharias glaucus, 
ten feet long, which had been observed in shallow water and driven ashore the previous night. 
A second remora was attached to the gills on the opposite side, but when disturbed it 
disappeared inwards by the branchial orifices, and was not seen again.” (Day.) 
Family CoryPpH&NIDA. 
Lampris LUNA (Gmel.)—Opah. 
(Day’s British Fishes, vol. I., p. 118, Pl. XLII.) 
The Opah, King-fish or Sun-fish, belongs to deep waters, and ranges from Scandinavian 
seas to the Mediterranean. It is also found in Japanese seas. 
It has been recorded from many places round the British coast, including Conway 
(Couch), Belfast Bay, Wexford, &c., on the shores of the Irish Sea. Byerley records that a 
specimen was caught in the estuary of the Dee in 1839, by a Hoylake fisherman; and the fish has 
since been taken at Rhos Neigr, on the coast of Anglesey.* 
Family CARANGID&. 
CARANX TRACHURUS (Linn.)—Horse-Mackerel. 
(Day’s British Fishes, vol. I., p. 124, Pl. XLIV.) 
The ‘‘Scad,” or Horse-Mackerel, is a migratory fish, appearing on the British coast 
from deep water in early summer, but apparently very variable. It rarely comes into the Irish 
Sea, but Parnell, in 1834, mentions prodigious numbers being on the Welsh coast. They are 
much commoner in most years on the Cornwall coast. Our fisheries steamer has taken it when 
trawling between the Lancashire coast and the Isle of Man. 
The species ranges from Norway to the Cape of Good Hope, and has also been found in 
Chinese and Australian waters, and at Valparaiso—a very wide distribution.
