eye side, where it is also thickest. For this reason 
English consumers set most value on “double” Turbots, 
i. e. those which are coloured on both sides. 
In Sweden the Turbot is known by many names. 
The Scanians say piggvarr or pifvare (cf. the Danish 
pigvarr); on Gothland and in the island-belt of Stock- 
holm it is called Butta , Botta or Potta (cf. the German 
Butte). Just as the Germans also call the Turbot Stein- 
butt, in Sodermanland, according to Ekstrom, it is 
known as Stenflundra , and in Stockholm, according to 
Malm, as Stenpotta. Pigghvarf or Pigghvarfvel (Spiny 
Fluke) is the name given it in Bohuslan.

The Brill and the Turbot are as closely related to 
each other as the Plaice and the Flounder — to choose 
one of the most prominent examples among the many 
that we might select from the preceding part of this 
work. In the great majority of the characters, too, the 
differences are parallel, so that in the following table 
we constantly find the percentage higher or lower in 
the Brill than in the Turbot, in exactly those characters 
in which we find a similar difference between the Plaice 
and the Flounder (cf. the above table, p. 407.) 
“ In very old (large) specimens, however, the percentage may be greater.
