It has been supposed that this is one of the many varieties 

 in which the Common Trout is prone to appear, as influenced 

 by differences in water and food, of which ah-eady we have 

 given an account; but observers who have been well qualified 

 to form an opinion, of which we refer to Dr. Parnell, Mr. Yarrell, 

 and Sir John Richardson, have confidently decided that it 

 is a distinct species; and from several particulars which they 

 have brought forward in support of this conclusion, we feel 

 no hesitation in adopting their decision; and so much the rather 

 as it is shown that there are abundance of the ordinary Trout 

 in the same waters, exposed to the same influences, but from 

 which the species above mentioned are readily to be distinguished. 



But although this fish has obtained its name from a particular 

 lake or district, to which indeed it was formerly believed to be 

 confined, we are not to conclude that it is not to be found 

 elsewhere, although perhaps in these kingdoms it may not be 

 known out of Scotland. Dr. Parnell's description was from a 

 specimen which measured a foot in length; the head rather 

 more than one fifth of the whole length, including the caudal 

 fin; the depth between the dorsal and ventral fins less than the 

 length of the head; gill-covers produced behind; end of the 

 maxillary (mystache) extending as far back as the posterior 

 margin of the orbit; teeth stout and sharp; vomerine teeth 

 passing along the whole way of the palate, thirteen in number. 

 Dorsal fin placed half way between the point of the upper jaw, 

 and a little beyond the fleshy portion of the caudal extremity 

 of the body, with tvv^elve rays; the third the longest. Tail 

 concave, with twenty rays; anal ten; pectoral twelve, ventral nine.
