The Report contains also descriptions and figures of various fossils, 
mostly from the carboniferous rocks, being species of several corals, 
achlopoda, (one species of ‘Terebratula, three of Productus, three of 
Spirifer, one of Chonetes, one of Orthis,) a few acephala, besides a 
, urotomaria and a Euomphalus, in all 14 new species. One species
