46 DR. A. GUNTHER ON THE BRITISH CHARRS. [Feb. 11, 
in colour, 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 we 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 with, 
or similar to, S. willoughbii; at all events by one very different 
from the ‘“‘ Haddy”’ of Loch Killin 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. YaRReELL, 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 differeut 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 Salmonide, and to 
give a more satisfactory account of them after having compared them 
with their congeners of the Continent. 
SaALmMo wiLLovcusu. (Pl. 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.
