Glabella slightly convex, the base broad, so as to form a nearly equilateral triangle. The sides are marked with three lobes, the posterior one being twice as large as the middle lobe, but the anterior one is ill-defined. The dorsal furrows are deep. The occipital ring triangular in front, and narrowing out later- ally. The frontal limb is broad, and equal to half the length of the glabella, and arched in front. It is worthy of remark that this character is not common to the minute glabella found in the same beds. The fixed cheeks have a buttress thrown across Fig. 3. them extending along the sides of the glabella, but this does not elevate them above it. The movaltle cheeks arc ti iangular in outline, and posteriorly extended into spines, and correspond to those figured by Prof Hall, Pal. N. Y., vol. ii, pi. 66 a, fig. 5, c.

The lateral lobes are not marked with ribs, as usual in Calymene, and in this respect the pygidium bears some resemblance to that of C. arago and C. salteri, two European forms found in the Lower Silurian, and descsibed by Rouau
