in width) and of semielliptical shape, stretched in width (L/W=0.6), strongly convex. It terminates with short and narrow genal spines rounded at the edges. The glabella is very convex, conical in shape, short (slightly less than 40% of the length of cephalon) and it narrows down from back end to front. The posterior part of the glabella is 2.6 times as wide as the anterior part. The basal lobes are very weakly defined. The entire surface of the glabella is covered with small round convex tubercles of different sizes, equidistant from each other and staggered. The occipital ring is long, narrow, convex. On its surface there are five or six large convex tubercles aligned in a row. The eyes are small, crescentic, and very prominent, located opposite the posterior half of the glabella. The palpebral lobes cover 1/3 of the eye. On either side of the glabella, a pair of large convex and detached tubercles is located at the top of the eyes. Posterior to them, between the palpebral lobe and the glabella there is a row of three other smaller tubercles. A number of variably sized tubercles are located around the eyes. The preglabellar field is generally flat though close to the anterior part of the glabella it rises steeply. The entire surface of cephalon is tuberculate. The largest, flattened tubercles are located closer to the marginal rim. They are more diffuse than the tubercles on the steep, central part of the cephalon - cranidia and regions of librigenae—on which the tubercles are denser and alternate with very small tubercles. The marginal rim is flat and very narrow, with 5 thin terrace lines on it.

in length), of semielliptical shape, wider than long (L/W=0.9), flattened. The rachis is long, occupying about 80% of the length of the pygidium. It becomes narrower towards the posterior margin (the posterior margin of the rachis is 6 times narrower than the anterior margin) and has a slight lateral narrowing nearer to the posterior end. The anterior margin of the rachis is three times narrower than the overall pygidium. In profile, the rachis is convex and subtriangular. It consists of 25 rings separated by deep and wide furrows. On each ring there is a row of 10 densely distributed large tubercles. The largest tubercles are located on the dorsal part of the rachis, and the tubercles decrease in size proportionally towards the dorsal furrows of the pygidium. In the posterior half of the rachis, on the dorsal parts of its five rings, there are large spine-like tubercles (broken off on all the specimens in the collection). The distance between them from the most rear to the frontal spine-like tubercle increases exponentially. The lateral lobes of the pygidium are nearly flat, and bear nine broad and long pleural ribs that are separated by wide and deep interpleural furrows which gradually widen to the marginal rim. In the anterior part of the pygidium, pleural ribs are almost perpendicular to the dorsal furrows, but as they approach the posterior end of the pygidium, the posterior pleural ribs become parallel to the dorsal furrows. The pleural furrows are distinct, deep, dividing the pleural ribs into a wider anterior and narrower posterior halfribs. The posterior half-rib is decorated with densely spaced, elongated tubercles aligned in a row. The anterior half is covered with chaotically located tubercles of different sizes, among which the largest tubercles are located closer to the dorsal furrows. The pleural ribs smoothly pass into a very narrow marginal rim which is devoid of terrace lines. The marginal furrow is absent. The marginal rim along its edge is densely littered with numerous small tubercles aligned in a single row.
