I just wanted to ask if you've seen the revised version of "Higher Taxa Of Extant Reptiles" of The Reptile Database: http://www.reptile-database.org/db-info/taxa.html#Ser
According to it Colubridae(and not only) is devided into few other families,including Natricidae! Does that mean we should have a "new" family in our gudes to european herps!?
