follow her for a long time. This larger form is always 

 found in deep water, 150 fathoms or so, whereas the 

 smaller one is principally taken off the coasts of Heli- 

 goland, and on hooks baited with the gadus esmarkii 

 (sma seg) and herring, in the summer, at a depth of 

 sixty to eighty fathoms. The flesh of the bergylt is 

 said to be delicious. Colour vermilion-red ; eyes bright 

 yellow; forehead between the eyes flat; its breadth 

 equal to -- in one eye diameter ; pectorals oval, thin ; 

 lower eight rays single, all joined by a web nearly to 

 the tips. Usual length of the southern specimens 18 in. 

 to 2 ft. It is singular that very small specimens of 

 this fish (under 8 in.) are even seen off these coasts.

 There is a smaller form in these seas, which Kroyer and 

 Ekstrom both think is a distinct species, but which Nilsson 

 considers only as a younger form of the common bergylt.

Pale reddish yellow, with a black spot on the tip of the 

 opercle, and a few indistinct dark spots on the sides of the 

 back. The points of the pectorals can reach back to the 

 anus. Length 8 in. to 10 in. 



The fin ray formula in both is much the same.

Has never yet been met with out of the Mediter- 

 ranean (where it appears to be common), except on the 

 west coast of Norway, where it goes as far up as Heli- 

 goland. It is always in deep water, and its Norwegian 

 name of ' ' skjar ver " proves that here, as well as in the 

 Mediterranean, it is principally found on rocky bottoms. 

 This species differs from the last in the narrower fore- 

 head, in the rays of the pectorals being only half- 

 covered with a web, a different fin ray formula, and 

 by the hinder part of the mouth being deep blue. Fore- 

 head between the eyes deeply furrowed, its breadth
