DEFINITION OF THE SUBJECT 3 



mal. This last is frequently omitted as it serves no pur- 

 pose except for the student of classification. Names of all 

 the various sub-divisions are Latin in form. Family names 

 always have the termination -id& and may be so recog- 

 nized as no other scientific names are given that ending. 

 Super-family names end in -ina, or -oidce, but are not so 

 distinctive, since other names may be found with similar 

 termination. Sub-family names end in -ince. Generic, 

 specific and order names may have any accepted Latin 

 termination.
