(lie distribution of the species, examples from Queensland, for example, 

 generally having fewer anal I'ays than others from NeAV South Wales.

 from near Sydney which appear to be similar in all details with others 

 from the Burnett River. The folloAving table illustrates the variation 

 of several characters in thirty-seven specimens from seven different 

 localities.
