572 LÖNNBERG, OBSERVATIONS ON CERTAIN FLAT-FISHES. 



The bastards are well known to the fishermen in the fishing- 

 places round Landscrona and they call them "horungar" to in- 

 dicate their illegitimate birth. The fishermen have even observed 

 that some of these bastards resemble turbot and others brill. 

 The colour of the fishes, and their scales are what the fishermen 

 judge from. 



For the sake of clearness I have stated in the following 

 tables, first, the number of rays in the fins, and secondly, the 

 respective measurements, of niy five specimens (numbered 1 — 5). 



Explanation of abbreviations: i = intermediate form; i,m^= 

 intermediate but a little nearer to Bothus maximus; i, rh = \nter- 

 mediate, but a little nearer to Bothus rhombus; m = withiu the 

 limits of the variation of Bothus maximus and rA = of Bothus 

 rhombus, all according to the table given by F. A. Smitt in 

 his great work (Scandinavian Fishes I, p. 442).
