. The Canadian naturalist and geologist. Natural history -- Periodicals. Foint Levi Fossils. 311 DiKELOCEPHALUS BeLLI. N, S. Fig. 7. Description,—Head semi-circular, the width apparently twice the length or a little more. Front margin surrounded by a nar- row convex rim, distant about its own width from the front of the glabella. The latter is obtusely oblong, conical rather convex well defined all round by the narrow groove of the dorsal furrows the sides nearly parallel,straight or nearly so,the front rounded. The neck furrow extends entirely across, nearly straight in the middle third and directed obliquely forward at an angle of about 45^ at the outer third on each side. In front of this, two oblique glabel- lar furrows on each side, their inner extremities separated bv about one third the width of the glabella, forming three lobes of nearly equal size. The eyes appear to be situated opposite the second pair of furrows from the front, and to be distant from the glabella about one third the width of the neck segment. Length of head of medium size, six lines and a half; length of glabella five lines and a half; width of the same at base four lines; a little narrower towards the front; width of marginal rim half a line; width of space between the marginal rim and the front of the glabella, half a line. Surface smooth. Cheeks, eyes, thorax and pygidium unknown. Dedicated to Mr. Robert Bell, the discoverer of the genus in the Canadian rocks Limestone, No. 1. DiKELOCEPHALUS MEGALOFS. N. S.
