ÖFVERSIGT AF K. VETENSK.-AKAD. FÖRHANDLINGAR 18 94, N:0 10. 573 



Of these five specimens N:o 1, N:o 2 and N:o 3 were, in 

 regard to the integument, brill-like turbots, or Bothus maximus 

 hybridus. The skin is farnished with densely scattered thick 

 sCales, or smooth tubercles. These are completely covered with 

 skin and most of them show "a low and blunt protuberance 

 behind, and with a groove running forward from this protu- 

 berance" (Smitt). These tubercles are smaller but higher in 

 the middle of the body and above the latei'al line. On the tail 

 and at the base of the fins they are larger in area, but not so 

 high; and more scale-like. They are also closer together, espe- 

 cially on the tail, so that the scales in the same horizontal 

 rows nearly touch each other with their visible parts. On the 

 praeoperculum the scales ^) are larger and flatter than on the 

 operculum, where they form small blunt tubercles in N:o 3, but 

 are fairly flat in N:o 1 and N:o 2. The scales on the blind 

 side are in all three specimens fairly large and flat, (only very 

 slightly raised) and are, depending upon their larger areas, closer 

 together than on the eyeside. In N:o 3 they are if anything a 

 little more tubercular. The scales of the vertical fins are, as a 

 rule, thin and flat, except that the scales of the anterior row 

 on each ray are a little convex. The colour of these three 

 specimens, when alive, was browmtinted with olive green. The 

 vertical fins are mottled darker, and a few fairly large but 

 indistinct spöts appear on the body; these, on specimen 2, 

 fall for the most part into two rows, one above and one be- 

 neath, parallel to the outer contour of the body. The blind side 

 is colourless. 



The specimens N:o 4 and N:o 5 inay be regarded as "turbot- 

 like brills" or Bothus rhombus hybridus. The scales on N:o 4 

 are much closer together than on any of the above-mentioned 

 specimens. The scales on the breast are quite close together, 

 thinner and nearly cycloid. The scales of the other parts of 

 the eyeside are larger and thicker and show more or less plainly 

 the posterior blunt protuberance and the anterior groove. The 

 ^) The "protuberance" and the "groove" are quite visible however.
