273 Part [1f.—Highteenth Annual Report 
and more or less generally distributed, especially in the deep-water 
area. The same may be said of the Argentine, Argentina sphyrena. 
This fish, which used to be considered a rare species in the Clyde, 
is really not very uncommon when sought for with suitable appliances. 
It may be pointed out further that if anyone were to look through 
the lists of Clyde fishes captured by the ‘ Garland,” he would fail 
to find a single record of a Halibut, which is only occasionally taken 
by a trawl. Moreover, the halibut is not mentioned for the Clyde in 
Dr. Giintier’s paper, nor in the work published by Harvey-Brown 
and T. E, Buckley already cited, yet the Fishery Officer at Girvan 
informs me that halibut are not very rare in the seaward part of the 
Clyde estuary, and that they are sometimes caught in the deep water 
off Ayr; while in a letter, dated the 28th December last, he states that 
he had seen, a few days before, a young halibut landed at Girvan, which 
had been caught between that place and Ailsa Craig, and which weighed 
about a stone. 
In looking through the statistics of the steamer ‘Garland,” it will 
also have been observed that Turbot and Brill are not very frequently 
mentioned in the lists of fishes captured by the steamer in the Clyde 
estuary, yet there is a more or less regular turbot fishery carried on off 
Girvan, and sometimes a considerable number of these fishes, captured in 
the Clyde by gill-nets, are brought to market. It is obvious from facts 
such as these that, though one mode of fishing may yield negative results 
in respect of certain species, it does not necessarily follow that these 
species are absent or even rare. The results obtained by the use of the 
ordinary beam or otter trawl are usually very different from those 
obtained by the use of special nets or lines, therefore a kind of fish that 
may be seldom or never captured by one set of appliances, may by the 
use of a different set be found comparatively frequent. 
The present enumeration comprises 113 species of Clyde fishes, but the 
occurrence of one or two of these appears to be somewhat doubtful; and itis 
also very desirable in the case of one or two others which, though their 
presence in the Clyde seems to be fairly well attested, further information. 
should be obtained concerning them. I have indicated such species by 
enclosing their names within square brackets, and also by the notes referring 
to them. 
There are several kinds of fishes which appear to be equally at home 
in the sea and in brackish water, and in some cases even in water that is 
fresh or nearly so; and there is a considerable divergence of opinion as to 
which, and how many, of these should be included in lists of marine 
species, and of those which should more properly be regarded as /resh- 
water forms. One has only to compare Professor H. G. Seeley’s interest- 
ing work on The Fresh-Water Fishes of Hurope with that of The British 
Marine Food-Fishes, by Professor M‘Intosh and Mr. A. T. Masterman, to 
find examples of this difference of opinion. In the present list there will 
probably be found species which, in the opinion of some people, should 
have been excluded as belonging more properly to the fresh-water group ; 
but when we find distinguished writers failing to agree on sucn a point as 
this, I may be excused if unable to prepare a list perfect in this respect. 
The basis of this list is the enumeration of Loch Fyne fishes, already 
referred to, prepared by the late George Brook, Hsq., and published in 
1886. | 
I have followed as far as possible the nomenclature used by Professor 
M‘Intosh and Masterman in their British Marine Food-Fishes, while the 
arrangement of the species is in accordance with that of the History of 
British Fishes by Dr, Francis Day.
