For those who are less familiar with the interior workings of the College of Cardinals: As Can. 350 §1 of the Code of Canon Law states:
The College of Cardinals is divided into three orders: the episcopal order, to which belong those Cardinals to whom the Roman Pontiff assigns the title of a suburbicarian Church, and eastern-rite Patriarchs who are made members of the College of Cardinals; the presbyteral order, and the diaconal order.
For more details see, e.g., EWTN's page on the Sacred College.
I have found some pictures of the occasion from the Osservatore Romano. The first two show the reception of the Cardinal at the door of the Cathedral, where he is given a Crucifix to kiss and then Holy Water to sprinkle those present, as foreseen for the reception of a bishop. The other images show the Cardinal during Mass, for which he wore a rather beautiful Roman chasuble and the pontifical dalmatic. The MC is Msgr. Francesco Camaldo, one of the papal MCs.
