page list – extra title

I wanted to exclude pages from my page list so this is the code I’m using in the left sidebar.

<li class="widget">
<h2>Pages</h2>

<ul>
<?php wp_list_pages('exclude=9,8,13' ); ?>
</ul>
</li>

As you can see from the website There’s an extra bullet with the word ‘pages’ next to it and all the pages I want listed underneath.
How do I get rid of that first bullet and the word pages. I’ve tried everything.

Thanks.
