half of the lateral line, and three smaller spots beneath them ; they are 
of sealing-wax red, just the same on right side ; two uppermost spots on 
adipose fin are scarlet, all the other spots on this side have a yellowish 
brown ring round them, with a whitish marking again surrounding it, 
rendering them beautifully ocellated. Upper third portion of body, dull 
stem yellow ; central third, rich gold of metallic brilliancy ; and lowest 
third of a rich “ buff orange,” or pale salmon colour ; extreme base, 
whitish buff. Irides, silvery, clouded with brown. The general colour 
of the right side is more uniform than above described, but lying on this 
side may have been the cause. On dissection the stomach and canal 
were found quite empty, excepting the ordinary thick mucus-like matter. 
The milt was of the thickest consistency. The vertebrae were fifty-six in 
number. 
Nov. 2 6th, 1840. Two fish, judged in the market from their hard sto- 
mach to be Gillaroos, were brought me. They were both Salmo ferox. 
The Great Lake Trout, Salmo ferox, Linn., 
Found throughout the larger lakes of Ireland ; attains upwards of 
30 lbs. weight ; is the common Salmo of Lough Neagh : particularly re- 
marked in this locality a century ago, and thought likely by authors to 
be identical with the S. lacustris of the Lake of Geneva see Proceedings 
Zool. Soc. 1835, p. 81. 
Florence Court, Oct., 1840. — Lord Enniskillen considers this fish the 
common trout of Lough Erne, as I consider it of Lough Neagh. He has 
seen one of twenty-eight pounds weight taken there. He caught it in 
Lough Melvin, Oct. 19th. A male fish three feet long, and weighing- 
twenty pounds, was caught in the neighbourhood (if in condition it would 
have weighed twenty-six pounds) ; it was about one foot in depth, 
and densely spotted from back to very near the belly ; the lower spots 
reddish. 
Mr. M‘Calla only knows this fish as found in Lough Corrib. (1840.) 
Ballyshannon, July 1 6th, 1840. — A gentleman living at Lough Melvin 
told me that trout are taken there of thirty- two pounds weight ; doubt- 
less of this species. * 
Salmo ferox. Sept. 22, 1836. Nov. 24, 1837. — Many S. ferox of me- 
dium size in Belfast market ; they were in bad condition, and many ova 
the size of the largest peas were scattered over them. For Dr. Scouler I 
bought two specimens (male and female) of similar size, weighing toge- 
ther 19 lbs. The marking was very different on the two sexes, the fe- 
male being of a silvery grey, densely covered over with black spots, the 
male not having half the number of spots, and which were bordered, chiefly 
the lowest ones, with a ring of dull orange. The general colour of this 
fish was very different from the female, the lower part of the sides and 
belly being of a rich salmon colour. 
On dissection there was not anything found in their stomachs but the 
backbone of a fish, which must have been about the size of a full-grown 
pollan ; the roe in female was the size of small peas and weighed alto- 
gether 17 oz. 
The stomach of a small S. ferox examined to-day contained remains of 
insects. 
* A specimen of S. ferox , sent to Dublin University Museum by one of the 
editors in 1854, weighed 32 lbs.
