> Marco,
 
Congratulations, your catalog of Mediterranean Rissoidae is great.  The
images are well done and format is easy to use.  You almost forget that we
are talking about grains of sand sized shells.  By the way, thanks for
including the size with each image, that is often left off and is critical.
 
Have a great holiday season,
