OUMNH Number: 74  
Name and quarry location: Marmo nero di Torino from the province of Turin, or more probably Portoro from the Porto Venere area, Liguria, Italy.  
Geological description: Black fine-grained limestone with a few thin yellow/white veins, and with distinctive black (organic matter?) veining.  
Comments: No obvious localities for black 'marble' have been found in the province of Turin, and so Corsi's locality is not confirmed. His specimen could be portoro from the Porto Venere area of Liguria, Italy.
