FOSSILS OF THE CAUnONIFEROUS LIMESTONES. 989 one of the limestones of the Windsor series, aiul is, I think, certainly new and undescribcd. The non-porifcrous side has thick parallel bifurcating ribs, with rounded surfaces finely striated longitudinally, connected by much thinner and rounded cross hars, enclosing oval fcnestrules. The poriferous side has the bars angular above, and with a central carina, beai'ing a row of small tubercles, which in the best specimens are seen to bear delicate spines. The pores are in two rows at the sides of the ribs. Its nearest allies are F, rctcforrnis, Schlol., and F. carinata, M'Coy, but it differs materially from both, more especially in its characteristic spines. Fenestella, another species, coll. J. W. D., Stcwiackc, with two rows of large contiguous pores. Resembles /''. Morrisii, M'Coy, but has the pores closer to each other. Fenestella with larger fcnestrules, not determinable. Coll. J. W. D., West River, Pictou. Bercnicea, Lamx.—Two species of encrusting Polyzoa occur on shells in Mr Ilartt's collections from Windsor. They may, in the meantime, be referred to this genus, but arc not determinable. Brachiopoda. The following descriptions of the Brachiopods of the Carboniferous limestones of Nova Scotia are extracted from Mr Davidson's paper above referred to, and the figures are from his drawings ;— " Terebrahda sacculus, Martin, sp., 1809, and varieties (Fig. 87), " Terehraiula dongata and T. sirfflata, De Verneuil, in Sir C. Lyell's ' Travels in North America,' vol. ii., p. 220, 1845; and in Dawson's 'Acadian Geology,' p. 219 (Fig. 27), 1855.
