skin, and appearing as rounded or oval protuberances. Dorsal (63) 69-72 (75) ;

 dorsal and anal with rudimentary scales on ocular side. Pectoral of ocular side with

The specimens described above appear to be genuine hybrids, and such forms would 

 seem to be not very uncommon in the Cattegat (Lonnberg) and on the Dutch coast 

 (Quelch). No e.xperimental evidence of their hybrid nature is yet forthcoming, but, 

 in view of the fact that they cannot definitely be assigned to either parent species, 

 and in certain features seem to be intermediate between the two, this would appear 

 probable. Further, the Turbot and Brill are closely related forms and spawn at about 

 the same time and in similar localities. Of five of such forms examined by Lonnberg, 

 two were males with well-developed testes, one was a female with a large ovary, and 

 two (the most essentially intermediate examples) showed no trace of reproductive 

 organs.
