is a little distorted, and plausible retrodeformations are also used herein. Cranidia are not transversely convex and would originally have been of similar width (tr.) along the posterior margin as they are long sagitally. Glabella occupies about 70% cranidial length (sag.), with maximum width across the frontal lobe close to 60% sag. length. Frontal lobe pyriform and extended (sag.), with anterior part in front of maximum width forming a semicircle in outline, and posterior part tapering regularly to level of glabellar tubercle; furrows defining it rather uniformly shallow. Although the furrows appear continuous the posterior parts are slightly deeper and here comprise the S1 glabellar furrow.

as a shallow furrow running more or less exsagitally. Hence the glabella is constricted at the level of the eyes to about two-thirds its maximum width at the front, and then widens posteriorly to a similar transverse width at the posterior margin. Prominent glabellar tubercle at one-fifth glabella length, opposite posterior part of the palpebral lobes, which are highly curved with weak rims, and of length (exsag.) one quarter that of glabella. Although they are close to the glabella there are small (exsag.) inflated areas adjacent to the palpebral lobes, which lie outside the axis. Postocular fixed cheek is very narrow (exsag.) proximally, wider laterally, and much of it is taken up by wide posterior border furrow that widens laterally. Preocular fixed cheeks merge with wider, flat preglabellar area. Facial sutures are recurved forwards behind the eyes, anterior branches diverging at about 40 degrees to sag. Line before curving adaxially in a smooth curve to meet at midline in a distinct point, so there presumably supramarginal. Free cheek not assigned. A hypostome (

Five pleural ribs, of which four are well defined, the fifth fainter, while the pleural furrows fade out over half-way across the pleural field. The pygidial axis is not well-preserved, but must have had narrow proportions (approximately three times as long as wide), and presumably a minimum of five axial rings to accord with the pleural ribs. The doublure, closely reflexed against the dorsal surface and carrying terrace ridges, extended quite far beneath the distal parts of the pleural furrows, but did not extend to the axis.

, showing five ribs which fade towards the pygidial margin and a similarly narrow pygidial axis. A paradoublural line on the largest pygidium indicates that the doublure closely approached, but did not reach, the axis. A sixth axial ring is observed and long terminal piece apparently without dorsal furrows. On the small pygidium there are faint indications of interpleural furrows, but their apparent absence in the large pygidia is probably accounted for by changes during later ontogeny.
