Registering post type is not adding to admin menu

Remove

'capability_type'      => array('slide', 'slides'),

This works

add_action( 'init', 'slides_post_type' );
function slides_post_type() {

register_post_type( 'Slides',
    array(
'labels' => array(
    'name'               => __('Slides', 'bonestheme'),
