�n this paper the content of tabulate corals of the Olorda �Lower Devonian� and �l Papiol �Mississipian� Formations near Barcelona (Catalonian Coastal Ranges, NE Spain) are described for the first time. The Olorda Formation was studied in the Bruguers section, where two new tabulate coral species, Petridictyum casanovai n. sp. and Procteria �Granulidictyum�? gavaensis n. sp., have been collected. The �l Papiol Formation was studied in the �l Papiol and Cánoves sections, and four tabulate coral taxa, Sutherlandia? sp., Smythina humilis �Hinde, 1896�, Palaeacis sp. and Cladochonus sp., have been recognised. �n addition, the succession of the Olorda Formation in Bruguers is described. Lochkovian-lowermost Pragian age is established for the B Member of this formation in Bruguers and this section is correlated with the t��pe section of the formation in Santa Creu d'Olorda. Finall��, it is deduced that the sedimentation of the upper part �B Member� of the Olorda Formation, in Bruguers, and the �l Papiol Formation, in the �l Papiol, took place on a mudd�� and soft bottom, t��pical of still waters, with scarce terrigenous supplies.
