MALACOPTERYGII. 
to him, that, in consequence of the preference shown for similar localities, 
the fish is in some places called Gravel-ing , he said that was the name 
applied to it by a gentleman from the South of Ireland; so, presuming 
this is the name there given to it, we have in this country two of its Eng- 
lish names — Parr in the North, and Gravel-ing in the South. 
I examined the stomachs of three parr and one trout, all of which were 
filled with the larvse of aquatic insects, excepting two or three flies ; no 
Crustacea appeared. There was ’neither milt nor roe apparent in any 
of them.

My friend Mr. Thos. Sin claire, who has been long accustomed to angle 
in the North of Ireland, and also in Scotland, states that the coloured 
figures (natural size) which accompany Mr. Yarrell’s paper on the Growth 
of the Salmon in Fresh Water correspond with his ideas of the salmon 
of every size represented ; but he is of opinion that a small fish which is 
taken in rivers during every month, from March to November inclusive, 
and which he calls the Parr , is a distinct species. He describes it as 
being of a more robust make generally ; more firm and strong than young 
salmon of the same size ; with scales not deciduous as those of the salmon 
are, and also devoid of the silvery appearance of the “ salmon fry.” The 
latter he considers to be always gregarious, and he has only taken them in 
April and May. Sometimes they rise so frequently and numerously in 
pools as to render the surface like a sheet of silver ; but he finds the parr 
scattered throughout the river in the same manner as the common trout. 
From the circumstance of his only meeting with what he considers the 
salmon fry in April and May, he reasons that they are only then in the 
rivers, although the parr are there at all times. 
In May, 1842, Mr. Sinclaire brought me, from Cushendall, a few fishes 
which he called parr, but, in consequence of their having been put into 
brine, they were unfit for critical examination. They all appeared to be 
evidently of the same species, and one of them, displaying a black 
pectoral fin and sharply forked tail, was, in my mind, a salmon ( S . Salar). 
The Grey Trout, Bull Trout, or Roundtail, Salmo Eriox, Linn., 
Is taken along the coast of the northern half of the island, and not 
improbably around the entire coast. A specimen captured in sea water, 
at Killala Bay, was sent to me by Mr. R. Warren, jun., in the autumn of 
1851. The first positive notice of this species as Irish was made by me 
to the Zoological Society in 1837, and published more fully in the first 
vol. of the Ann. Nat. Hist., vol. xxxv. 7, as follows : — ■ 
“ Salmo Eriox, Linn., Bull Trout. — Dec. 3, 1836. — In Belfast market I 
selected from a basket filled with sea trout (S. Trutta ), in high condition, three spe- 
cimens of S. Eriox, which were taken along with them in the sea at Donaghadee, 
in the County of Down. Their length is from 19f to 21 inches : weight of each 
about 2flbs. Two are males, having the lower jaw very slightly hooked,* the 
other is a female ; the operculum differs much in the sexes ; teeth on the vomer 
of one male and the female three in number, in the other male four ; teeth gener- 
ally much smaller in the female than in the males. Fin-rays, with one or two 
exceptions, are in the three specimens — D. 14, P. 14, V. 10, A. 11, C. 19. 
“ In colour they are silvery grey, having but few spots (of the form X XX 
and purplish black) above the lateral line, and scarcely any below it. Donovan’s 
* In the Fauna Boreali Americana it is remarked, that “ the hook of the 
under jaw is very decided, even in a young Salmo Cambricus,” (Part iii. p. 307,) 
but in the present instance the reverse appears.
