Note on the Reproduction o/Ligula. By M. Brulle. 



M. Brulle has made a communication to the Academy of Sciences 

 of Paris, stating that he has found a new mode of reproduction to 

 prevail in a species of Ligula, which infested the Bleak {Cyprinus 

 alburnus) in the Canal of Burgundy, in great numbers during the 

 past summer. The Ligulce have generally been regarded as Cestoid 

 worms which passed a first, asexual stage of development in the 

 interior of the bodies of freshwater fishes, and only acquired repro- 

 ductive organs when they reached the intestines of birds. According 

 to M. Brulle's statement, it appears that the Ligulce, contrary to the 

 generally received opinion, are capable of producing living, Cerca- 

 riform young whilst still parasitic upon fishes ; he saw one of these 

 worms which he had just extracted from the body of a Bleak, pro- 

 duce two or three young ones, which, he adds, " resembled the 

 parent, except that the anterior portion of their body was broader 

 and thicker than the opposite extremity. They may be compared.
