These rocks, with the same general structure, arc widely distii- buted in Southern New Hrnnswick, but, as might be expected, they vary in detail, more especially in the upper mend)ers. 'J'hey also present a general resemblance to the belt of lliiper Silurian rocks already referred to as extending towards Uathurst, and rocks of this type are known to occur in the I'ljper Silurinn districts of Nova Scotia. The fossils found in the lower members of this series near East- port arc a Lingidn allied to L. ceulrilincata of the Lower llelder- bcrg, and also very near to some Hamilton species, and to that found in the T,ower Devonian of (Jaspe, though probably difl'ereut from that occurring in the Upper Silurian of Wcntworth, I'ictou, and Arisaig. There are also species of ModioDiorp/ia, and a species of , with a small Beijrichin of lJ])pcr Siiurian type. Elsewhere in New IJrunswick these beds have all'orded sj)ecies of S(i\)p/iume)ia, Ort/iis, Rhynchonella, Pterinea. and corals of Upper Silurian genera.
