FISHES. 571 



The Wliiff. Scales in the outer margin rounded, and 

 rough on the top. In an oblique row above the lateral 

 line 26 to 30 scales can be reckoned ; under that, 24 to 

 26 ; on the lateral line., behind the curve, 64 to 66 scales. 

 If the lateral line is drawn straight, at least ten scales lie in 

 a row above that and up to the curve. 



Ekstrom's Topknot. Scales angular, only finely crenated 

 on the outer edge. In an oblique row above the lateral line 

 18 scales; under it about 20; on the lateral line about 36 

 slimy scales. If this is drawn straight, 4 to 5 scales lie in a 

 row above it up to the curve. 



150. K. HIETUS, Yarr. LudenHvar. Miiller's Topknot. D. 



Roundish oval ; only the eye side of the body rough ; 



. edges of the scales crenated; jaws equal; the first 



dorsal ray not longer than the preceding ones ; ventral 



and anal fins united ; the dorsal and anal fins connected 



to the tail, by a membrane ; eyes close together. In 



other respects, resembles the turbots. Usual length 



9 in. ; greatest height equal to half of the length. 



Is met with sparingly, at all seasons of the year, in the 



Sound and Cattegat, and on the north-west coast of Norway, 



at least as far up as Bergen. Of its habits little appears to 



be known. 



Blocks topknot (P. unimaculatus, Bl.), which has never 

 yet been identified on these coasts, has been probably over- 

 looked. It may always be distinguished from Muller's top- 

 knot by the elongated first ray of the dorsal fin, by both 

 sides of the body being rough, by the large eyes, and the 

 separation between the ventral and anal fins. 



Gen. Solea, Cuv. 



Eyes to the right ; no anal spine ; dorsal commencing at 

 the mouth, and reaching, as well as the anal, quite to the 

 caudal. 



151. SOLBA VULGAEIS, Cuv. Tunga. The Sole. D. 



Oblong; eyes wide apart; scales small and rough. 

 Colour of the upper part of the body dark brown ; pec-
