first of all it cannot remove using layout because this content is not coming from layout object
...It is coming from category
object
if you need this remove then got catalog/category/view.phtml...
put some logic to hidden this.
Just commit below code which
is show title
<div class="page-title category-title">
<?php if($this->IsRssCatalogEnable() && $this->IsTopCategory()): ?>
<a href="<?php echo $this->getRssLink() ?>" class="link-rss"><?php echo $this->__('Subscribe to RSS Feed') ?></a>
<?php endif; ?>
<h1><?php echo $_helper->categoryAttribute($_category, $_category->getName(), 'name') ?></h1>
</div>
Or if you want for for a category then you can do
this using below step:
1)create replicate of view.phtml as name customview.phtml and in customview.phtml commit title code
.
2)add below on which set customview.phtml as it template
here 49 particular cat id
<CATEGORY_49>
<reference name="category.products" >
<action method="setTemplate"><templatecatalog/category/customview.phtml</template></action>
</CATEGORY_49>
