 males, f, h, k and I females. g and i were sterile so that 

 not even their genus could be discerned. The males from

 pearly excrescences of the spawning-season and similar al- 

 though not so great and so numerous also occur on specimens 

 h and I, although they are females. Specimen d and h re- 

 present a golden variety called the »princely vobla» by the
