To piggy-back off Ahmad's use of Extension Methods, you can create your own class where the list is private with a public get method and a public add method.

public class MyList
{
    private List PrivateSomeClassList;
    public List SomeClassList
    {
        get
        {
            return PrivateSomeClassList;
        }
    }

    public void Add(SomeClass obj)
    {
        // do whatever you want
        PrivateSomeClassList.Add(obj);
    }
}

However, this class only provides access to List<> methods that you manually expose...hence may not be useful in cases where you need a lot of that functionality.
