I find your question a bit confusing, sorry for that. But let me guess, you mean, for example directory "blah" has permission -wx--x--x. And you wonder, why it is readable (getting information about it, inode etc) but we are unable to list the content? Simple then, have you consider the permission of the directory which contains "blah" directory? suppose it's "super_blah" and it has rwxr-x-r-x, then of course we can read the information of "blah" itself but unable to list the content of "blah" due to its own permission.
