    are well shown. I have called it Woarwoyensis, from the name of the locality, where it is found in abundance, and was first disco- vered by me, viz., Woarwoy Bay. Length = 1-33 in. Breadth (auterior) = 0-49 „ „ (posterior) = 0*52 „ Figure 8, Sanguinolites Woarivoyensis.—This species in some re- spects resembles the S. sulcatus of Phillips, to which it is allied. Posteriorly, the ridges are as well marked as in S. sulcatus; but the bifurcation is much less distinct, and the species is considerably smaller. Length = 043 in. Breadth = 1-07 „ The beds in which these fossils occur are characterized by a well- marked group of fossil remains, which occupy a definite position immediately above the plant sandstones. The following are the most abundant of the species:— Orthis crenistria. Atrypa fallax. Reticularia (S]p.) Productus caperatus. P. antiquatus. Modiola Woarwoyensis. Sanguinolites Woarwoyensis. Actinocrinus (-Sp.) The beds just described are succeeded by thick beds of yellowish sandy limstones, alternating with gray flaggy sandstones and shales, which are literally covered with fragments of fishes' teeth; and these beds are again succeeded by others containing abimdant casts of fucoids. The total thickness of the fish teeth and fucoid beds is 71 feet. The remainder of the older limestone beds of this district which underlie the dolomite beds, are composed of flaggy limestones, with black shaly partings, and alternating layers of blue shaly limestone. The total thickness of the series, including the two groups al- ready mentioned, is 851 feet. About the middle of the series, a band of fine shaly limestone occurs, under Loftus Hall, which contains an extraordinary abundance of two varieties of Carboniferous Trilobites, viz., Phillipsia gemmulifera and P. qxiadriserialis.
