Fio\ 36.—Two specimens of the glabella of a small trilobite from the Chazy Limestone ; genus not determined. 37.—Fragment of Bathyrus Angelini. 38.—Harpes antiquatus. The eyes as indicated by the course of the facial suture, are large, crescentiform, and a little more than one-third the whole length of the head. The anterior angles of the eyes appear to be a little in advance of a line drawn across the glabella at half its leno-th, while the posterior angles are a little in advance of the neck-furrow. The thorax is not well known. From several fragments of it the central lobe appears to be cylindrical, strongly convex, a little wider at the anterior than at the posterior extremity. The pygidium is strongly convex, and closely resembles that of B. extans. Allied to B. extans (Hall, sp.), but that species has the poste- rior spines of the glabella of great length, extending backwards to the pygidium. Dedicated to M. P. Angelin, the eminent Swedish Palaeonto- logist. Locality and Formation.—Grenville; Chazy limestone, Gren- ville and Fitzroy Harbour. Collectors.—J. Richardson, Sir W. E.
