285 Part I1I—EHighteenth Annual Report 
being used, Halibut are occasionally recorded at Ballantrae caught by 
cod or turbot nets. I have no doubt a stray specimen is also got between 
Arran and Ayr, although I do not at present remember of more than one 
cwt. being landed at Ayr this year.” 
Drepanopsetta plattessoides, Fabr. The Long Rough Dab. 
‘‘Many adults and young (2 inches in length) were obtained in 26 to 
46 fathoms in Kilbrennan Sound in December. Many adults and young 
were also taken between Cumbrae and Wemyss Point in 30 to 40 fathoms 
in February 1888” (Giinther). The long rough dab is very common and 
generally distributed throughout the Clyde area, especially off shore and 
in moderately deep water. 
Bothus maximus (Linné). The Turbot. 
“One captured in the Clyde area, August 28th, 1888; formerly 
numerous there” (Giinther). Turbots have been taken in the trawl-net of 
the Fishery steamer “Garland” in the vicinity of Ailsa Craig, in the 
vicinity of Sanda Island, and in Kilbrennan Sound. Occasionally taken 
in Loch Fyne (B. & S.). There is a regular turbot fishery carried on off 
Girvan, a special net called the “turbot net” being used for the capture 
of the fish. 
Bothus rhombus-(Linné). The Brill. 
The brill is rather more frequently recorded amongst the lists of 
fishes captured by the Fishery steamer “Garland” than the turbot, 
but mention is not often made either of the one or the other. The 
largest specimen of the brill referred to by Day is one recorded by 
Thompson, which measured 24 inches in length. The “Garland” has, 
however, obtained even larger specimens than that ; one 25 inches was 
captured after nightfall at Station VII. on May 21st, 1897. <A few 
measuring 21 and 23 inches have also been taken at different times. 
| Zeugopterus unimaculatus, Risso. One-Spotted Topknot. 
“‘One specimen in 10 fathoms off Ardrossan, Clyde area, in April 
1888” (Giinther). Several specimens were captured in a shallow sandy 
bay at Barmore, Loch Fyne, in 1885 (B. & S.). (Two of these specimens 
are still in the collection of fishes at the Fishery “Board Laboratory, Bay 
of Nige, Aberdeen. 
Zeugopterus punctatus (Blainville). Miiller’s Topknot. 
“Clyde area, 60 fathoms” (Giinther). Upper Loch Fyne in 10 to 25 
fathoms (M.). Zeugopterus punctatus has been taken in the trawl-net. of 
the “ Garland” in the vicinity of Ailsa Craig and in Kilbrennan Sound. 
Rhombus norvegicus, Ginther. The Norway Topknot. 
Dr. Giinther records the following specimens from the Clyde :—One 
dredged in Lamlash Bay at a depth of 6 to 18 fathoms, measuring 34 
inches in length, and in excellent condition ; one smaller than the last, 
caught off the Cloch Lighthouse in 43 fathoms; and one 34 inches long, 
caught in Kilbrennan Sound in 45 fathoms. (See also Dr. Giinther’s 
_ description of the larger of these specimens,*) The Norway topknot is 
occasionally taken in the shrimp-trawl of the “Garland,” but it appears to 
be a rare species in the Clyde.
