Of the genus Salmo, Ireland possesses all the British spe- 
cies. There are many valuable fisheries for §. Salar around 
the coast; of the migratory species, S. Trutta is next in value, 
and is taken co-extensively with it; the distribution of S. 
Eriox is yet to be determined; on every side of the northern 
peten of the island it occurs. S. ferox is common to the 
arger lakes, as is S. Fario to the rivers and lakes throughout 
the island. Salmo Umbla or S. Salvelinus (for I regard the 
fish so called but as one species) inhabits suitable lakes in all 
quarters. The Osmerus Eperlanus is recorded by Templeton 
as a fish of occasional occurrence. Coregonus Pollan, as yet 
known only as an Irish species, inhabits Lough Neagh, Erne, 
and Derg, and is abundant in the first-named locality. 
Of the six species of British Salmonide, as yet unknown as 
Trish, three, Osmerus hebridicus, Coregonus Willughbei, and 
Cor. Lacepedei, are each known only to a single locality ; 
Scopelus Humboldtii (if such be the species) has been re- 
corded but in three instances on the coast of Great Britain; 
Thymallus is very local in England. This is noticed in Rutty’s 
Dublin, but evidently in error, as it is made ‘a sea-fish.” 
Dr. P. Browne enumerates it, perhaps without any better 
reason; he published in 1774, Rutty in 1772. Coregonus 
Lavaretus (if properly so named) is found only in Bala Lake 
in Wales, and some of the northern English lakes.

Clupea Leachii and C. alba have not yet been identified as 
Irish species; nor has the Engraulis, which is of rare occur- 
rence on the English coast, been noticed on the Irish. 
Clupea Harengus, C. Sprattus, and C. Pilchardus prevail 
around the coast, the last-named in the south particularly ; 
here also the Alosa Finta is chiefly found. The “ Rock Her-
