In this case, yes there is.  Some work has been done to develop an  
index of all the genera.  Tony Rees has been working on a list of  
genera http://www.obis.org.au/irmng/ and GBIF has funded some initial  
work on developing an All Genus Index.  The current estimate from the  
latter is closer to 400,000 than 300,000 based on a collation of  
genera indices from a number of nomenclatural sources.   We will  
proceed with its refinement over the course of next 6 months.  While a  
comprehensive list of genera arranged within some phylogenetic  
structure would be a very useful referent dataset, we have very  
practical and applied usages for such a structure that motivate us to  
proceed.

By "this" do you mean a list of genera?
