Page tab visibility for visitors vs. members

I do not want the subscribers to my site to have to see the page tab for "Register" for example.

Similarly, the Welcome page that a new subscriber might see after they finish the registration process ... I do not want a visitor to see that as an available tab. When I say "available tab" I mean the bar at the top where users can click on "Home" "Account" "Blog" "Sign Up" etcetera.

How do I fix this visibility?
