It is sometime desirable to indicate other groups than those named 
above. Thus a family may be divided into subfamilies, or an order 
into suborders. And occasionally an even more minute division is 
made. Thus several closely-allied families may be grouped together 
as a superfamily, a group of lower rank than a suborder. The follow¬ 
ing table includes all the grades of groups now commonly employed :

VI. Zoological Nomenclature. 
(For advanced students.') 
At the beginning of his studies of Natural History the student is 
met with what is to him a new and strange set of names. These 
names are often long. In form they belong to a dead language, with 
which, in these days, even many educated people are unfamiliar. It 
is not strange that we often hear complaint respecting the difficulty of 
this nomenclature.
