THE SALMON FAMILY, 349 



lateral line. Colour : sides with red dots ; belly red ; pectoral, ven- 

 tral, and anal fins with white margins. 



In a male fish of 11 inches in length, described in detail by Dr. 

 Giinther, the number of fin-rays were — 



D. 12 : A. 12 : P. 13 (or 14) : V. 9 (or 10) *. 

 The nostrils were situated immediately before the eye, the hinder 

 nostril widest ; and the cutaneous bridge between both not deve- 

 loped into a flap. Maxillary bone extending slightly beyond margin 

 of orbit, armed with from 20 to 21 teeth of moderate size ; 4 teeth in 

 each intermaxillary, 17 in each mandible, 2 pairs (4) on vomer, 15 on 

 each bone of palate, and 4 pairs (8) on tongue. Scales very small and 

 thin, those on the back minute and hidden in skin. Gill-covers 

 silvery, lower parts minutely dotted with black ; edges not overlapping 

 root of pectoral fin, which is entirely free. Vertebrae 59. 



The Grey Chaer, or Fresh-water Herring of 

 Lough Melvin, Ireland. 



This Charr appears to be confined to Lough ]\Ielvin; 

 and the account we have of it is stOl incomplete, and can 

 be considered only as a first step towards a satisfactory 

 history of the species. The flesh is said to be white and 

 softj and different from that of the Charr of any other 

 lough ; but this peculiarity may possibly depend upon the 

 state of the fish at the time of its being caught, as a 

 recent writer on the subject mentions that he has found 

 specimens not inferior in point of firmness, flavour, and the 

 pink colour of the flesh to any Charr in the kingdom. 



Dr. Giinther gives the following as its general charac- 

 teristics : —
