GANOIDEI. 
Prof. Kner examines the characters by which this order has 
been defined, and shows that not one is generally applicable to 
the various forms referred to it. He says that the order, as in- 
troduced into the system, is not a natural unity, that it must be 
more limited, if it he kept up, and that its establishment not 
only did not advance the development of a natural system, but 
impeded it. The author does not propose an emendation of the 
system, but indicates that systematists should be more careful 
in observing Linnean principles in characterizing systematic 
groups, and pay more regard to the genesis of the various forms.
