| Comments: |
Corsi's specimen matches very closely a sample in the Pescetto Collection in the Servizio Geologico d'Italia in Rome which the published catalogue (Corpo reale delle Miniere, 1904) gives as 'Monte Rufoli (Volterra)?' It is less brecciated than no.730, which is clearly from the same locality.
