Dareste confirms Syrski’s views respecting the male organs of the Eel 
discovered by him, but finds that the variety (the ‘Pimpernau*) in 
which they exist also exhibits female organs in other individuals ; this 
which is a purely marine variety, would thus be the agent in the 
reproduction of the species ; the larger individuals which ascend the 
rivers being sterile, i.e., the eggs never arriving at maturity. He has 
found male organs also in Anguilla marmorata from the Indian seas.
