ON THE FAUNA OF IRELAND. 385 
In the family Percide, Ireland would seem to be so deficient 
that four species only can be announced; of these, Mullus 
Surmuletus is given on the authority of Dr. Patrick Browne’s 
Catalogue, published in 1774. The Perca fluviatilis is stated 
to have been introduced; but this I am disposed to doubt, as 
the species is so very widely distributed over the island. 
Labrax Lupus is a well-known fish on the coast, its numbers 
decreasing northwards. Trachinus Vipera is found from 
north to south. 
Of the species unknown to the Irish Fauna, Serranus Ca- 
brilla and §. Gigas have in Great Britain been noticed only 
on the coast of Cornwall, and of the latter but a single in- 
dividual has been procured; Polyprion cernium has been 
observed only on the south-west coast of England; Mullus 
barbatus is extremely rare; Trachinus Draco a species only 
of occasional occurrence, and chiefly on the southern coast*. 
Acerina vulgaris is said to be common to the rivers and canals 
in England.

Of the seventeen (reckoning Zrigla Gurnardus and T. 
Cuculus as one) British species of Loricata here enumerated, 
Ireland is known to possess all but five; of these, three spe- 
cies, Trigla lucerna, Peristedion Malarmat, and Cottus qua- 
dricornis, are late additions, and have as yet been procured only 
* The term “ southern coast” applied to England, throughout this Report, 
refers generally to the portion of that country which lies altogether to the 
South of Ireland.
