c. Species 



Table VI includes 57 characters separating the species in at least one of the three 

 genera in which more than one species was available for study. The characters 

 operating taxonomically within a particular genus are indicated by the mark 



X ", and those not operating by the mark " O ". The table shows that the 

 species of these genera could be separated by a large number of characters including 

 differences in the development of various structures, the number and distribution 

 of the setae and disc pores.
