It's in Behavior.  The hierarchy for Array and Array class looks like:

Instance Protocol             Class Protocol
----------------------------------------------------------
Array                         Array class
Arrayed Collection            Arrayed Collection class
Sequencable Collection        Sequencable Collection class
Collection                    Collection class
Object                        Object class
(nil)                         Class
                              ClassDescription
                              Behavior
                              Object
                              (nil)


You can find this by doing a "spawn protocol" in the class browser pane 
when the switch is set to Class (to see the class protocol as opposed to 
the instance protocol).
