698 DR. A. GUNTHER ON THE CHARRS OF BRITAIN. [Nov. 28,

Cuarrs. Parrlll. By Avsert Ginruer, M.A., Pu.D.,

(Plate XL.) 
Since the publication of my last paper on British Charrs* I have 
received, among other examples, a most remarkable form, which, in 
the excessive development of its fins, differs from all the other species 
known to me from Great Britain and the continent of Europe. Only 
Salmo grayi from Ireland and S. nivalis from Iceland approach it in 
the length of the pectorals; but the former cannot well be con- 
founded with it, having much larger scales and the body compressed 
and rather elevated; from the latter it differs in several points of 
minor importance, and especially in the increased number of pyloric 
appendages, which, besides, are extremely narrow and slender. For 
specimens of this Charr I am indebted to Mr. Gould, to whom they 
were sent by Mr. Hanbury Barclay, and who informs me that they 
inhabit a very retired loch in Inverness-shire, Loch Killin, about 
2000 feet above the level of the sea. They are caught only in 
September and October, when they approach the edge of the loch 
to spawn. 
This Charr was already known. to the late Wm. Thompson, in 
whose work on the Natural History of Ireland, iv. p. 164, we find 
the following note :— 
« About fifteen miles from Loch Corr is Loch Killin, situated m the 
pastoral vale of Stratherrick. Three specimens of char have thence 
been brought me. They are remarkably different from the Loch 
Corr example, are of a clumsy form, have very large fins like the 
Welsh fish(?), and are dull in colour, of a blackish leaden hue through- 
out the greater part of the sides, the lower portion of which is of a 
dull yellow; no red appearing anywhere. So different, indeed, is 
this fish from the char of the neighbouring localities, that it is believed 
by the people resident about Loch Killin to be a species peculiar to 
their lake, and hence bears another name,—‘ Haddy’ being strangely 
enough the one bestowed upon it. This fish is only taken when 
spawning, but then in great quantities, either with nets or a number 
of fish-hooks tied together, with their points directed different ways. 
These, unbaited, are drawn through the water, where the fish are 
congregated in such numbers that they are brought up impaled on 
the hooks. The largest of my specimens is 16 inches in length, and 
others of similar size were brought to my friend at the same time— 
on the 26th or 27th September, when about a ‘ cart-load’ of them was 
taken. The flesh of some was white and soft. They contained ova 
the size of peas. On dissection my specimens were found to be male 
and female; externally the sex could not have been told with cer- 
tainty. Their stomachs and intestines were empty. This fish bears 
a resemblance to the Lough Melvin char, but differs from it in some 
characters,”
