It is evident that a table n liicli enumerates 308 species and 

 extends over several pages is fai- too unwieldy to convey a 

 correct impression of the outstanding features of distribution. 

 The principal table of distribution is therefore supplemented by 

 two tabular lists, which will serve as a summary and at the same 

 time emphasise the points which are most striking. The first 

 supplementary table supplies the number of species represented 

 in each la.ke classified under their respective families.
