APPENDIX. | Fishes. 369 
PaGELLUS CENTRODONTUS [ 7'he Sea-bream]. 
This is a more common sptcies—numbers appearing annually. 
In some seasons they appear in greater abundance than in others. 
They are sold here under the name of “perch.” 
Brama Rau [Ray's Bream]. 
Rare. 
CantHarus eriseus [The Black Bream]. 
A few of these are generally procured every autumn, or about the 
beginning of winter. They are known and sold here under the 
term of “old wife.” 
Dentex vuLearis [The Four-toothed Sparus]. 
Although this species, like many more, bears the name “vulgaris,” 
or common, it is not so with us. I am only aware of one speci- 
men, which was taken off Troup Head. 
Scomper scomsrus [ T'he Mackerel]. 
This beautiful and highly prized fish generally appears on our 
part of the coast about autumn; in some seasons, in great 
plenty ; in others, not so numerous. 
Scomper corras? [The Spanish Mackerel ?] 
As will be seen, I have placed this species here as doubtful. A 
mackerel differing in many respects from the one noted above, 
and which agrees very well with Scomber colias, was taken off 
Portknockie, but by the time I had the pleasure of seeing it, it 
was a good deal disfigured. Still, as I have already said, it ex- 
hibited many of the markings and other characteristics of the 
Spanish mackerel. 
Taynnus vuiearis [The Tunny]. 
Several specimens of this fish have, from time to time, been taken 
with us. A very large one was captured in a salmon-net at Port- 
soy. It measured over nine feet in length, and six feet in girth. 
Xupwias Giaprus [ The Sword-fish]. 
A small specimen of this fish—rare on this part of the coast—was 
caught in our harbor by a shrimper. 
Navcrates puctor [ The Pilot-fish], 
A very fine specimen of this rare and rather peculiar fish was 
taken in our bay some years ago, and was exhibited as a curi- 
osity. It was unknown in the place, and also to the person who 
took it; but an old tar chancing to see it, who had seen some 
service abroad, having hitched up his trousers, and rid his mouth 
of a yard or two of tobacco-juice, exclaimed, with something of a
