285 Part III — Eighteenth 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 Eough 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 (Linne). 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 -(Linne). 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 Nigg, 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, Giinther. 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 3^ 

 inches in length, and in excellent condition ; one smaller than the last, 

 caught off the Cloch Lighthouse in 43 fathoms ; and one 3^ 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.
