46 DR. A. GTJNTHER ON THE BRITISH CHARRS. [Feb. 11, 



in coloui'j and in the size of the head and of the fins (in the number 

 of the vertebrae, the male having 60, the female 62-63 ?) ; number of 

 ova, 482. Beside a detailed description of the colours, the account 

 does not contain anything from which vfe could determine the species. 



2. Of other localities in Scotland, Loch Inch and Loch Corr are 

 mentioned. They appear to be inhabited by a species identical vs^ith, 

 or similar to, S. willoughbii ; at all events by one very different 

 from the " Haddy" of Loch Kilhn in Invernesshire. The latter is 

 very interesting, inasmuch it appears to be closely allied to the 

 Freshwater Herring of Lough Melvin. They are only caught when 

 spawning, about the 26th of September. 



3. The freshwater Herring of Lough Melvin appears to be con- 

 fined to that locality. 



4. Lough Dan (county Wicklow, Ireland) is inhabited by a Charr 

 " presenting some of the characters both of the northern and Welsh 

 Charr." Specimens were caught in summer with the fly. 



5. Other localities in Ireland are — L. Kindun, L. Gartan, L. Derg, 

 Lake of Luggela, Loughnabrak, and L. Corrib. The Charrs from 

 those localities have 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 Inchigeelagh (co. Cork), and 

 one or two other small lakes in this neighbourhood; L. Neagh* ; 

 a lake near Dunfanaghy (co. Donegal); L. Eaghish (co. Monaghan). 



1841. Yarrell, in the first edition of his work, distinguished, 

 according to the view of Donovan, a S. umbla and a ^S. salvelinus, 

 adopting afterwards the opinion of Agassiz and Thompson. His 

 account is composed of the observations of the different writers men- 

 tioned. As new localities, are mentioned Keswick, Crummock 

 Water, Coniston Water, Loch of Moy, Loch Inch, &c. The Gilt 

 Charr is mentioned as a variety of the Red Charr. 



I conclude this paper with the descriptions of three species, which 

 certainly are not the only ones by which Great Britain and Ireland 

 are inhabited. I look forward with great hopes for the assistance 

 kindly promised by various friends of natural history, trusting that 

 with their help I shall finally be enabled to make up a complete 

 series of specimens from all the localities which are inhabited by 

 this obscure and therefore so interesting group of Salmonidcet and to 

 give a more satisfactory account of them after having compared them 

 with their congeners of the Continent. 



SalMO WILLOUGHBII. (PI. V.) 



(The Charr of Windermere.) 



Body compressed, slightly elevated, its greatest depth being one- 

 fourth of the distance of the snout from the end of the middle caudal 

 rays ; the length of the head is a little more than one-half of the 

 distance of the snout and of the vertical from the origin of the dorsal.
