Package listed in MELPA, but not found in package install

I had to run M-x package-refresh-contents. Once I did that, the files were found.

Here’s what my .emacs looks like:

(cond
 ((>= 24 emacs-major-version)
  (require 'package)
  (package-initialize)
  (add-to-list 'package-archives
           '("melpa-stable" . "http://stable.melpa.org/packages/") t)
  (package-refresh-contents)
 )
)
