This appears to be the only freshwater sponge hitherto recorded 

 from Africa south of the Zambesi. In Eiirope and X. America the 

 species is one of the commonest, and it has also been recorded from

 from India is L\ meyeni (Caktek), whicli is, however, more closely 

 allied to E. mülleri Leberkühn. Weltner ^), indeed, regards it as 

 a variety of that species and is probably correct in so doing.
