io6 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." 



Trevelvan's Char {Salvelmus 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, 

 lonsdalit) 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
