. Catalogues of the Silurian fossils of the island of Anticosti, with descriptions of some new genera and species. Paleontology; Paleontology. 64 surface of all is covered with small closely crowded tubercles just visible to the naked eye. Junction Cliff; Div. 1, A. G. J. Richardson, T. C. Weston. Genus Harpes, Goldfuss. H. CONSUETUS, n. sp.—This species is of the ordinary form of the genus. Contour of the head including the border and spine ovate, broadly and uniformly rounded in front, gently convex along the sides, and narrowing sRo-htly backwards from a line downwards at the neck furrows to the extremities of the spines. The border is gently concave, with an abruptly elevated wire-hke marginal rim all round. All that part which lies in front of the neck segment is not quite a perfect semicircle. The body of the head is moderately convex; glabella rather small, regularly conical; dorsal furrows deep along the sides, rather shallow round the front; neck furrow all across; an obscurely developed pair of lobes at the neck furrow; the depression on each side in front of the neck furrow small. The eyes are small and situated on a line drawn across the glabella at a little less than one-third its length from the apex, and at about one-third the width of the glabella from the dorsal furrow. Surface unknown. Length from the front margin to a hne drawn across the tips of the spine, twelve lines; length of the head six lines ; Avidth at the neck segment, ten lines ; length of the glabella, three lines ; width of the same at the base, two lines ; Avidth of the border of the head, two lines. The specimen consists of a mould of the head from which good gutta percha casts have been obtained, giving the whole form very nearly. This species is closely allied to H. Ottawaensis, but is narrower, the head not so convex, and the depressed space on each side of the base of the glabella smaller. South-west point; Div. 4, A. G. J. Richardson.
