' THE MYXOGASTRES* 
When Rostafinski published his Monograph of these organisms, 
in 1875, it was supposed that the subject was settled, for some 
time to come. In Natural Science there is no such thing as 
finality, and it was not long before it was discovered that in this 
instance there was opportunity for improvement. Suggestions and 
emendations followed each other, without departing greatly from 
the systematic method adopted by Rostafinski, and now we are 
face to face with a “ Monograph ” which proposes a modification 
of that method. It will be remembered that, in the former, the 
primary divisions were the Amaurosporce , with spores violet, or 
brownish violet, and the Lamprosporce, with spores diversely coloured, 
never violet. Each of these subdivisions were again subdivided 
into Atiichce, sporangia without a capillitium, and Trichophorce , 
sporangia constantly possessed of a capillitium. Under each of 
these the order, families, and genera were grouped. In his
