It was found by Mr. AlbertG. Hill, manager of the Cumberland Coal-mine,at the South Joggins in Nova Scotia, in one ofthe bands of black bituminous limestone which Fia. 1. occur in the middle part of the Coal Formation. Trans. Glasgow Geol. Soc. 1866, vol. ii. pp. 68-69, pi. iii. figs. Drawn by Mr. G. H. Emerton, and reproduced by Principal Daivson—On New Pakeozoic Crustacea. 57 It is associated with shells of Naiadites carhonariiis and N. elongatus[Anthrucomya of Salter) and with cara-paces of Cythere and Bairdia. The specimen is a flattened carapace,without any of the other parts. Itslength, without the rostrum, is 0-9 rostrum projects 0-25 inch. Theextreme breadth is 0-85 inch. Thesurface is smooth at the sides, but pa-pillose in the median portion. As com-pared with the published figures anddescriptions of P. duhius, its distinctivecharacters appear to be :—1. The shorterrostrum and larger spines at the anteriorangles. 2. The reduction of the denta-tions on the anterior part of the sides tofive in number. 3. The presence of twostrong spines in front of the cervicalgroove at each side of the base of therostrum, and parallel to it, and ratherless than half-way between it and thelateral margins. Whether the dorsalridge extended to the posterior margincannot be seen, as this p
