Note: We draw attention to Avrzus bleekert described 
by Dr. Canna Popta (Notes Leyden Museum XXII 1go00, 
p. 71) after 4 specimens of unknown habitat, found by her 
among fishes, forwarded by the late Dr. Bleeker to the 
Leyden Museum, as there is a chance, that it may be an 
indo-australian species.
