1 06 BRITISH FRESHWATER FISHES 



taken in other lakes. Its differing from the so- 

 called char, in being an insipid bad fish for the table 

 and pale in the flesh, is the chief reason of its being 

 considered distinct from it." 



TREVELYAN'S CHAR (Salvelinus trevelyani} was 

 described from a single male specimen, 8 inches in 

 length, figured on PI. XIV, Fig. I. This was sent 

 to me in 1906 from Lough Finn in Donegal, by 

 Major H. Trevelyan. It is distinguished from Cole's 

 Char by the longer head, narrower interorbital 

 region, produced pointed snout, and strong denti- 

 tion. 



I have recently received a second smaller example, 

 a female, from Captain J. S. Hamilton, which proves 

 that in this form the sexes differ considerably, for, 

 having a smaller head, a shorter and blunter snout 

 and weaker teeth than the male fish, this specimen 

 is quite as similar externally to a male Cole's Char 

 as to the male of its own species. 



Of the British species the Haweswater Char (S. 

 lonsdalii) shows considerable resemblance to this 

 one, but has the snout shorter, the teeth smaller, 

 the fins larger, etc. Char have been recorded, but 

 not described, from a number of loughs in northern 

 Donegal, and it may be that Salvelinus trevelyani is 

 the species which inhabits them. 



SCHARFF'S CHAR (Salvelinus scharffi\ from Lough 

 Owel in Westmeath, was recently described by me 

 from one example, nearly a foot long, in the collec- 

 tion of the Dublin Museum, lent to me by Dr. R. 

 Scharff. This species has the broad head and short 

 snout of Cole's Char, from which it differs in that
