You are either missing a quote before ";" or you have an extra one before "ls".
Assuming you have set up key based authentication and the remote machine identity is known, what you are doing will work fine (until some horrid network condition breaks it):
perl -e '$foo=`ssh myhost "ls /tmp/bar/"` ; print $foo. "\n"; '

Oh, errors too:
perl -e '$foo=`ssh myhost "ls /tmp/bar/" 2>&1` ; print $foo. "\n"; '
