Paulina's chapel at St. Maria Maggiore; two of oriental granite in St. Pudenziana; one of transparent oriental jasper in the Vatican library; four of Nero-Bianco, in St. Cecilia Transtevere; two of Brocatello, and two of oriental agate in Don Livio's palace; two of Giallo Antico in St. John Lateran, and two of Verdi Antique in the Villa Pamphilia.

Specimens of brocatello may be found in several churches and palaces, forming mouldings, sheathings, and pedestals. The most interesting of the Lumachella marbles is the bianca antica, the Marmor Megarense of the ancients, composed of shells so small as to be scarcely discernible, and so closely compacted that the substance takes a good polish.

Their substance is formed of the shells of the common oyster in bluish gray and black particles on a white ground, as in the Lumachella d' Egitto; of the cardium or cockle, assuming a lighter or deeper shade of yellow, as in the Lumachella d' Astracane; of the ammonite, as in the L. Corno d' Ammone; of the Anomia ampulla in the L. occhio di Pavone, so called from the circular form of the fossils whichever way the section is made; of encrinites, belemnites, and starfish, showing white or red on a violet ground, as in the L. pavonazza; and "of broken shells, hardly discernible, together with very shining and saccharoid particles of carbonate of lime," as in the Marmor Schiston of the ancients the brocatello antico of the Italians, so named from its various shades of yellow and purple, resembling silk brocade.

Domenico e Sisto and Santa Pudenziana, where they appear among the marble sheathing of the walls. In the chapel of the Gaetani in the last-mentioned church, the wall is incrusted with the richest marbles, especially Lumachella and Brocatello, and large tablets of Hadrian's breccia setting off the splendid sarcophagus of Breccia nera e gialla dedicated to Cardinal Gaetani.
