THE GILLAROO TROUT. 
1 55 
It does not occur in the Baren. 
One which I got was taken in the eel-net at Toome, the other two be- 
tween Shane’s Castle and the Six-mile Water. These three, and one I saw 
in Belfast market, had large scarlet spots, ^ of an inch in diameter, from 
lateral line towards the belly, which partook more or less of a golden 
colour. None of the other trout approximating these in size were 
coloured at all like them in either of the above characters. 
The fishermen consider them inferior to the other Salmonidce for the 
table. 
March 2Ath, 1835. — I purchased in Belfast market a specimen of this 
fish from Lough Neagh ; its dimensions, &c., are as follows : — Length, 23 
inches; weight, 4i pounds; depth, 5£ inches. B. 11 at one side, 12 
rays at other; D. 2] 12 ; P. 14; V. 9 ; A. 2| 11 ; C. 19. The two last rays 
springing from same base, in D. and A. fins, are reckoned as 2. 
Irides, silvery, clouded with black ; colour, similar to what it is in 
autumn, but not quite so intense, having several large scarlet spots on 
and below lateral line. Towards the belly it is of a rich golden colour, 
tinged with a faint blush of rose colour ; under parts white, becoming 
deeper in colour towards the vent, where it is cream-coloured. D. fin 
spotted over; C. of different shades of brown, with upper portion spotted, 
terminated by a regular band of yellowish brown ; P. fins tipped with 
amber brown ; Y. and A. tipped with yellowish brown ; upper jaw projects 
over lower when the mouth is closed. I took two specimens of Paludina 
impura from its mouth . * 
August 21th, 1836. — Mr. Hyndman states that a Gillaroo from Lough 
Neagh, opened by him to-day, contained ova the size of small peas. 
April 8th, 1835. — I purchased a Gillaroo trout in Belfast market of 1 lb. 
weight, which was caught in Lough Neagh. Its length is 14 inches. 
Breadth, 3-L inches. B. 11 at one side, 12 at the other ; D. 2| 11 (last ray 
double from base) ; P. 14; V. 1|9 ; A. 2110 (last ray double from base) ; 
C. 19. Irides, silvery tinged with yellow, very faintly clouded with black. 
Body of fish same colour as usual, though scarlet spots however appear. 
The roseate, golden colour of this specimen, below lateral line, is, as in 
all other specimens I have seen, quite peculiar ; head spotted over the top. 
P. and Y. fins of an amber colour, A. fin exhibits a tinge of pale amber, 
C. not regularly banded as in last specimen : see bottle for contents of 
stomach which was opened in London. Vertebrae 54. April 25th, 1841. 
My attention was arrested, in passing through the market, by a Gillaroo 
trout, its aspect, with the deep golden sides (lower portion of), being very 
conspicuous. Its small teeth too were displayed. I purchased it for the 
Museum. It is two feet in length ; from the aesophagus to the anus it 
was entirely filled with Paludina impura and Valvata oblusa, they nearly 
filled a large tea-cup. Contents of the stomach very thick, fish very fat, 
the cceca were imbedded in actual fat. 
Oct. 18th, 1836. — I examined the contents of the stomach of a Gil- 
laroo, put up for Dr. Scouler, and found it to contain only (excepting 
a minute pebble) specimens of Gulnaria lacustris, which were of middle 
size, and upwards of eighty in number. 
Oct. 3rd, 1837. — I bought a Gillaroo of seven pounds weight from Lough 
Neagh. It is 27 inches long and 6 inches deep. D. fin begins 11^ inches 
from snout ; V. 1 inch behind it ; Adipose fin 1 inch 10 lines long. On 
the left-hand side it has but four scarlet spots, which are on the hinder 
* This is the specimen I gave Mr. Yarrell; he has figured it.
