RE: Two New Systematics Papers

["Williams, Tim" <TiJaWi@agron.iastate.edu>]

Can anyone tell me what journal the abbreviation "Exs" refers to?  It's
probably really obvious, but I can't seem to figure it out:

> Ranhy Bang, T.R. Schultz, Rob DeSalle, 2002. 
> Development, homology, and systematics. 
> Exs 92:175-188 
>
> S.E. Stanley & J.L. Cracraft, 2002 
> Higher-level systematic analysis of birds: current problems and possible
> solutions.
> Exs 92:31-44

Many thanks in advance


Tim
