296 THE PRACTICAL FISHERMAN. 



(2) In specimens from Loch Menin both sexes are coloured alike, nor 

 can they be distinguished from each other by the size of the fins. 



The difference observed in the charrs from other localities is not 

 pointed out. Dr. Giinther considered Mr. Thompson's paper as highly 

 important to our knowledge of the geographical distribution of the charrs 

 in Great Britain. 



(1) A charr is found in Loch Greenock, Kirkcudbrightshire, which 

 makes its appearance only during ten days, never before about the 13th 

 of October. The sexes are distinct from each other in colour and in the 

 size of the head and the fins. Of the vertebrae the male has sixty, the 

 female sixty-two or sixty-three. Besides a detailed description of the 

 colours, the account does not contain anything from which we could 

 determine the species. 



(2) Of other localities in Scotland Loch Inch and Loch Con are men- 

 tioned. They appear to be inhabited by a species identical with or 

 similar to 8. Willoughbiia,t all events, by one very different from the 

 " Hoddy " of Loch Kullin, in Inverness-shire. The latter is very inte- 

 resting, inasmuch as it appears to be allied closely to the freshwater 

 herring of Lough Melvin. They are only caught when spawning, 

 about the 20th September. 



(3) The freshwater herring of Lough Melvin appears to be confined to 

 that locality. 



(4) Lough Dan, county Wicklow, Ireland, inhabited by a charr " pre- 

 senting some of the characteristics both of the northern and Welsh charr." 

 Specimens caught in summer with the fly. 



(5) Other localities in Ireland are L. Kindun, L. Garten, L. Derg, 

 Lake of Luggela, Lough Nobruk, and L. Corrib. 



The charrs from these localities had a deep red belly, and appear 

 to approach S. Willoughbii or S. Cambricus. 



(6) The following localities in Ireland are named on the authority of 

 other writers : L. Esk (co. Donegal) ; Cummeloughs, in the mountains of 

 Cummeragh ; Lake of Inchbegreelah (co. Cork) , and one or two other 

 small lakes in the neighbourhood ; L. Neagh, a lake near Danfanaghty 

 (co. Donegal) ; L. Eaghish (co. Monaghan). 



In 1841 Tarrell distinguished, according to Donovan, 8. unibla and 

 8. salvelinus, adopting, in subsequent editions of his work, the opinions 

 of Agassiz and Thompson. His account is composed of the observations 

 of the different writers mentioned. New localities are referred to Kes- 

 wick, Cummock Water, Coniston Water, Loch of Moy, and Loch Inch. 



Having thus, with gratitude, made such use of Dr. Giinther 's elaborate 

 treatise, I beg leave to further lay him under contribution in a technical 

 description of the three recognised species. I do this with the less hesi-
