I have to agree with you there.  I would have much prefered to see Reptilia 
dumped altogether as a formal taxonomic name.  However, as matters currently 
stand, Reptilia and Sauropsida are two different groups.  Mesosaurs and 
potentially all of the non-turtle "anapsids" and even many basal diapsids (if 
turtles really are diapsids) are sauropsids but not reptiles.
