Siehe zuvor L, IN'ature und Alluaiid. — The Medusa in the Victoria 

 Lake is identical with that in Tanganyika, and its presence in the former

 should be found along with the jelly fish, oder die Meduse ist erst 

 dorthin übertragen worden owing to the opening up of the new trade 

 routes, and the carriage of water in gourds and other vessels from one 

 basin to the other.
