GEN. SALMO. THE GEEAT LAKE TROUT. 141 



the Lochleven Trout have lately fallen off in flavour 

 and condition, owing, it is supposed, to the partial 

 drainage of the loch having destroyed some of the 

 best feeding grounds. Dr. Parnell says that he has 

 seen specimens of this Trout from Sutherlandshire, 

 a circumstance which prevents us supposing that it 

 may have been introduced to Lochleven from the 

 Continent. The specific name, first imposed by 

 Walker, has been retained as having the right of 

 priority, and although a local one, being more aD- 

 propriate than one taken from an internal and very 

 variable part of structure. 



(Sp. 129.) S.ferox. Great Lake Trout. .Al- 

 though this fish has been long known to anglers in 

 the great lakes of Scotland and Ireland, it is but 

 recently that it has been fully described, and had 

 its proper place assigned to it in our native Fauna. 

 For this we are chiefly indebted to Sir W. Jardine, 

 by whom its characters were first carefully investi- 

 gated and defined. There can be no doubt, we 

 should think, of it being distinct, as a species, from 

 the other Trouts of this country ; and we hive the 

 authority of M. .Agassiz for affirming that it is not 

 identical with any of the continental Salmonidae. * 

 Sir W. Jardine's description first appeared in tlie 

 article Angling, by Mr. Wilson, in the last editr.n 

 of the Ency. Brit. The head is large and length- 



* Mr. Yarrell, however, is of opinion that it is identical with 

 the great Trout of the Scandinavian lakes, some of whicn, 

 weighing from twenty-seven to thirty-four pounds he had 

 lately an opportunity of examining.
