94 BRITISH FRESHWATER FISHES 



long and in the males usually projecting, and the 

 teeth rather strong ; the interorbital region is quite 

 flat, and narrower than in the Windermere Char. 

 The example figured (PL VIII, Fig. i) is a male, 

 gh inches long, from Llanberis. 



In the summer months the Torgochs appear in 

 shoals on the surface of the water, their dorsal fins 

 just showing ; they are then occasionally taken with 

 a fly, but the best sport is obtained in September 

 and October, fishing with a worm, either from a 

 boat or from the shore ; in this way as much as 

 45 lbs. has fallen to one rod in a day. 



At Llanberis the lower lake, Lyn Padarn, is deep 

 and has a rocky bottom, and towards the end of 

 November the Char pass up the small stream which 

 connects the two lakes in order to spawn in the 

 shallows at the lower part of the upper lake, Lyn 

 Peris. It was said by Pennant that the Char of 

 Llanberis had all been destroyed by water from the 

 copper mines, but he was evidently mistaken. 



The Struan Char {Salvelinus struanensis), of 

 Loch Rannoch in Perthshire, is known to me from 

 fine examples, 7 to 8 -J inches long, three males and 

 two females ; the largest of these, a male, is figured 

 on PL X, Fig. I. This species differs from those 

 previously considered in the short blunt snout and 

 inferior mouth ; the rounded lower jaw is shorter 

 than the upper and included within it when the 

 mouth is closed ; the maxillary is short and broad, 

 only reaching the vertical from the posterior edge of 

 the pupil and measuring but little more than one- 

 third of the length of the head ; the teeth are feeble ; 

 the eye is large, its diameter measuring one-fourth
