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 :

II. 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 w^e often hear complaint respecting the difficulty of 

 this nomenclature.
