In N:o 2 the first ray of the dorsal is Fig. 2. 



more deeply branched and provided with three 

 free ends. (Fig. 2). The foUowing rays have 

 also two free ends, but they are short in this 

 form as well, and not very divergent from 

 the turbot type. 



The corresponding rays of the dorsal of 

 N:o 3 are similar to those of N:o 2 bnt the 

 ülaments of the second ray are more deve- 

 loped and the rays themselves are a iittle 

 larger than in the foregoing specimen (Fig. 3). 



In N:o 4 the three first rays of the dorsal are still more 

 deeply branched, they are moreover softer and pj,^ ^ 



not a Iittle larger (Fig. 4). Their bases still 

 resemble those of a tm-bot and even their 

 distal ends have not yet got that broad pal- 

 niated appearance of those of the brill, but 

 at the same time they are not so closely 

 connected by the web as tliose of a turhot 

 usually are. 



The first part of the dorsal of N:o 5 is nearly the same as 

 that of a brill (Fig. 5). The first ray is divided half-way into 

 two. These branches are themselves repeatedly branched again. 

 Thus this first ray of the dorsal is as much Fig. 5. 



branched as in a genuine brill. ^) Its base is 

 also quite similar to that of a brill, as it is 

 smooth and rounded, and nearly cylindrical; 

 moreover it is not provided with a weblike 

 keel towards the blind side as the following 

 25 — 30 rays in this form are and the corres- 

 ponding ones in the brill too, and all the anterior rays, even 

 the very first ones in uiy other bastardforms, and in the turbot 



^) It thus reseaibles certain iilgae or a uolony of Flustra in miniature, because 

 the ends *' the mys are free from the web but flaltened and a liltle mem- 

 branens at the margins.
