referrlble to one variable species. This may be 

 briefly distinguished from the other members of the 

 genus in the manner stated by Dr. Parnell ; namely 

 from 'S'. fario, S. Levenensis^ and S. trutta, by having 

 only the anterior part of the vomer armed with 

 teeth ; and from S. eriocc and S. salar^ by the body 

 being marked with red or white spots. The head 

 is nearly one-sixth of the whole length, including 

 the caudal fin, the depth of the body greater than 

 the length of the head : the anterior part of the 

 dorsal fin is half way between the point of the nose 

 and the adipose fin, the latter placed rather far back. 

 All the fins are of comparatively small size, the 

 axillary scale very long, the tail deeply forked. 

 The formula of the fin rays is,

The colour of the back is dark olive, the sides 

 lighter, and spotted with either red or white : the 

 belly and all the fins on the under side, deep red-

The weight of this fish is commonly under a

 upwards of two pounds. Some of the varieties 

 spawn about Michaelmas, ascending for a short way

 in the end of December and deposit their ova in 

 the shallow parts of the lake. The Charr occurs in 

 all the three kingdoms, although it is by no means 

 generally distributed. The northern lochs of Scot-
