ing to Mr. Pennant in Llyndivi *, a lake in South Wales, and called 
Cock y dail, is marked with red and black spots as big as sixpences ; 
Trout with spots conspicuously large, but not so considerable as those, 
we have taken in plenty in the Dee river, Merionethshire. In tire 
Eynion, a river not far from Machynlleth in the latter county, and 
also in one of the Snowdonian lakes, according to the Hon. Dailies 
Barrington, are found a variety of the Trout which is naturally de- 
formed, having a crookedness in the tail, more decidedly characterised 
than in the common Perch t. The Trouts of certain lakes in Ireland, 
such as those in the province of Gailaway, known by the name of the 
Gillaroo Trout, are remarkable for the great thickness of their sto- 
machs, though do not differ in other respects from the common 
Trout!. There are certain Trouts in the lakes of Scotland that are 
spotted very differently from the common sort, those we shall not 
enumerate among the varieties of the common Trout, as we suspect 
they may be of a distinct species. 
With regard to size, the Trout varies greatly: its ordinary length 
is about twelve inches. Old Walton records the Fordidge Trout

t Hr. Pennant had an opportunity of comparing one of the Gillaroo Trouts, with a 
large one from the Uxbridge river; the last was, if he recollects, smaller and out of season, 
and its stomach, notw ith;, landing it was very thick, was much inferior in strength to that of 
the former ; but on the whole there was not the least specific difference between the two 
subjects. Penn. Brit. Znol. The thickness of the stomach of this fish proceeds, no doubt 
as Pennant imagines, from the superior quantity of shell fish which it finds in the waters it 
inhabits, and which may cal! more frequently for the use of its commuting powers tha»
