Get "Description" field from SharePoint Document Library using Client Object Model

Question

I'm using the following code:

ClientContext ctx = new ClientContext("SiteUrl");
List lst = ctx.Web.Lists.GetByTitle("DocumentLibraryname");

CamlQuery cq = CamlQuery.CreateAllItemsQuery();

ListItemCollection lic = lst.GetItems(cq);

ctx.Load(lic, items => items.IncludeWithDefaultProperties(
        item => item.DisplayName,
        item => item["Description"]));

ctx.ExecuteQuery();

foreach (ListItem l in lic)
{
    Console.WriteLine("title: {0}, DisplayName: {1}, Modified: {2}, Description: {3}", 
                        l["Title"], l.DisplayName, l["Modified"], l["Description"]);
}

If I were to remove the "item => item["Description"], and l["Description"] the rest of the results would be returned. What is special about the Description field in a SharePoint document library? How can I return the contents of a Description field?

Thanks in advance.

SharePoint has two types of names for columns, the internal names and the display names. "Description" is more likely the "Comment" internal field.

Here's a list of SharePoint 2010 internal field names, as well.
