How to add a new custom resource to routes Rails 3

Question

How do I add a custom route for a new resource in the Rails 3 routes?

I know how to do it for collections and members but this style doesn't seem to be working for new resources. Is this a bug or am I doing something wrong?

So these work:

collection do
  get :wish
end

member do
  get :wish
end

But this doesn't work:

new do
  get :wish
end
