270 cole's chak. 



a pair of stouter teeth in front of the palate, where in one 

 example there were three teeth; none on the vomer; two rows 

 of strong teeth, five in each on the tongue; a veil in front on 

 the under jaw. The body deepest opposite the origin of the 

 dorsal fin, and this depth is greatest in the male, although the 

 female was filled with enlarged roe, the grains of which were 

 almost as large as those of a Salmon. Lateral line straight; 

 scales on the body small. Dorsal fin large, behind the centre 

 of gravity, with thirteen rays; anal wide, with twelve rays; and 

 in both these fins the last rays spring from one root; adipose 

 fin small. Pectorals large, pointed, in length a little less than 

 from the snout to the border of the gill-covers, eleven rays; 

 ventrals large, the rays ten; tail wide, forked, with nineteen 

 rays. Colour on the head and back dark, with a tint of blue, 

 softening off at the sides; deep reddish orange at the belly; 

 gill-covers bright, with a tint of blue. Pectorals, ventral and 

 anal fins tinged with orange — the last-named fins in one example 

 with a white border in front; adipose fin reddish orange; tail 

 and dorsal fin dark. In the male the colours were deeper than 

 in the female. 



Comparing the colours of these examples with those of the 

 Torgoch, as given by Donovan; the latter spotted with red on 

 the back and sides, and with white on the red belly, and all 

 the fins red except the dorsal, and even that partly so; the 

 difference between these fishes, where colour is of so much 

 importance, is easily discerned; added to which he represents 

 the lateral line as being dotted with white; and the nostrils 

 are not placed in a deep depression as in our fish. Mr. Yarrell 

 also says that in the fish he describes the beginning of the 

 dorsal is half way between the point of the nose and the adipose 

 fin, which is far from the case in the Enniskillen Char; and 

 he says further, that the pectoral is small, while in our fish 

 the length of this fin is only a little less than from the snout 

 to the border of the gill-cover. Compared with an example of 

 the Melvyn Char of the length of ten inches and a half, the 

 latter is of a stouter form, the head more sloping down, gape 

 larger, fins larger, and the tail especially so; and while in the 

 former the pectoral fin runs only a little beyond half way to 

 the root of the ventrals, and the origin of the dorsal is above 

 the point of its termination, in the last-named it runs more than
