is also peculiar ; the lower jaw is not, or scarcely, 

 shorter than the upper, the eye is rather large, and 

 the fins are well developed. The colour of the 

 back and sides, with the dorsal and caudal fins, is 

 bluish grey, that of the belly silvery or orange; 

 orange spots are present on the sides. 



This is a small species, attaining a length of 8 

 inches; the male example figured (PI. XII, Fig, i) 

 measures an inch less. 



Cole's Char {Salvelinus colli), originally described 

 by Dr. Giinther in 1863, from Lough Eask in 

 Donegal, is now known to inhabit the neighbouring 

 Lough Derg, several lakes in Connaught, Lough 

 Gortyglass in Clare, and Lough Currane in Kerry. 

 In Donegal and in the small lakes of Connemara it 

 grows to a length of about 8 inches, but in Loughs 

 Conn, Mask, Corrib, and Gortyglass specimens a foot 

 long are to be met with. 



Cole's Char is almost identical with the Winder- 

 mere Char, and were it not that it exhibits very 

 constant characters in widely separated localities 

 in Ireland, it might well be placed as a race of 

 6". wlllughbll. It has the body moderately elongate 

 (the greatest depth contained four to five times in 

 the length of the fish, without the caudal fin) ; the 

 caudal peduncle rather slender, its least depth about 

 two-fifths the length of the head ; the snout sub- 

 conical, decurved, with the jaws equal anteriorly ; 

 the mouth moderately large, the maxillary extending 

 a little beyond the eye in males of 1 2 inches ; the 

 interorbital region a little convex and broad (its 

 width one-third the length of the head in the adult 

 fish) ; the pectoral fins not very long, extending
