Part III — Eighteenth Annual Report 



Centrolabrus exolefus, Linne. Small-mouthed Wrasse, Rock Cook. 



Taken occasionally in Loch Fyne (B. & S.). 



Corisjulis (Linne). The Rainbow Wrasse. 



Recorded for the Clyde area on the authority of Dr. J. Young (H.B., 

 p. 200). 



Order ANACANTHINI. 

 Fam. Gadid.e, Cuvier. 



Gadus callarius, Linne. The Cod. 



Common and generally distributed. The natural habitat of the cod 

 is in moderately deep water ; this is shown by the fact that if they are 

 exposed for a lengthened period to daylight their eyes become more or 

 less diseased. When at Rothesay Aquarium in 1886-87 I observed that 

 the eyes of almost all the specimens of cod kept there were diseased, and 

 one specimen was entirely blind and had to be fed separately. This 

 disease, which at first took the form of an opaque white spot, but which 

 gradually extended all over the eye, was ascribed to the fish being kept 

 exposed to the daylight. The cod were the only fishes in the Aquarium 

 that were affected in this way. 



Gadus segleftnus, Linne. The Haddock. 



More or less frequent, and generally distributed throughout the Clyde 

 area, but much less abundant than on the East Coast. Upper Loch Fyne 

 in the centre in 65 to 70 fathoms (M.). j between Pennyinore and 

 Inveraray (G.). 



Gadus luscus, Linne. The Bib, or Whiting Pout. 



Occasionally in Tarbert harbour (B. & S.) ; Tarbert Bank, Lower 

 Loch Fyne ; and between D.underawe and Cairndow, Upper Loch Fyne 

 (G.). Generally distributed'throughout the Clyde estuary, but seldom 

 more than 8 to 10 inches in length. Two, 13 inches in length, were 

 obtained near Sanda Island in May 1897. A specimen in the Fishery 

 Board's collection in the Laboratory at Bay of Xigg measures fully 15 

 inches in length. 



Gadus mimdus, Linne. The Poor or Power Cod. 



Dr. Giinther in his paper on Clyde Fishes states that "the specimens 

 obtained on March 10th and 17th were ready to spawn, and had fed on 

 Nydijphanes, sand eels, and Aphrodite." This Gadus is usually more or 

 less in evidence amongst the contents of the shrimp-trawl of the Fishery 

 steamer " Garland." 



Gadus esmarkii (Nilsson). The Norway Pout. 



According to Dr. Giinther, the distribution of this species in the Clyde 

 extends from Kilbrennan Sound to Lower Loch Fyne, where young 

 specimens were found in tolerable abundance at 80 fathoms. He also 

 remarks that " tlie species does not appear to be unfrequent in Kilbrennan 

 Sound." He states further that " the characteristics by which Gadus 

 esmarkii can be distinguished from its British congeners are : — The lower 

 jaw, which projects beyond the upper; the dentition, the teeth of the outer 

 series in the upper jaw being a little larger than the inner ones; the
