Create a view/list of pages made with Panels I know how to view/list particular content types in a View:

I just need to add a "filter criteria" to the View that will display all node belonging to that type.

cool. but, I can't figure out how to view/list particular pages made with Panels.

Pages made with Panels are not selectable from the "filter criteria" box in the View.
Try www.yoursite.com/admin/structure/pages

This lists all the system generated &amp; custom panel pages that exist.
