LOCHLEVEN TROUT.

It has been supposed that this is one of the many varieties 
in which the Common Trout is prone to appear, as influenced 
by difierences in water and food, of which already we have 
given an account; hut observers who have been well qualified 
to form an opinion, of which we refer to Dr. Parnell, Mr. Yarrell, 
and Sir John Eichardson, 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 fiom 
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-eovers 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 twelve rays; the third the longest. Tail 
concave, with twenty rays; anal ten; pectoral twelve, ventral nine.
