is illustrated herein, and is reasonably well-preserved, although the tip of the fixed cheek is not present. Glabella occupies three-quarters of cranidial length (excluding occipital ring), and is as wide as long; occipital ring 25% total glabellar length. Glabella best preserved on right side showing convex flanks narrowing forwards to broadly arcuate front. Deep S1 with outer end at three-eighths cranidial length, curving inwards but fading well before occipital furrow, distally not quite becoming exsag. S2 follows in line with inner part of S1, and shallower, its anterior termination just behind a prominent anterior pit at the end of the axial furrow. L1 is twice as wide and twice as long as L2, and both somewhat inflated. Occipital ring well defined, narrows laterally, and carries a prominent circular median tubercle. Preglabellar field as wide (sag.) as border in front near midline, and widens towards corner of glabella. Palpebral lobe situated about 40% of the distance across the adjacent glabella, and of similar length (exsag.) to preglabellar field (sag.). Eye ridges strong and convex, directed back at about 60 degrees to sag. line.Anterior border furrow of even, moderate depth along its length. Border hardly convex and gently bowed forwards. Posterior border furrow as deep as axial furrows, and posterior section of fixed cheek presumably broadly triangular. Facial sutures diverge at a low angle in a convex curve in front of the palpebral lobes and at a high angle behind. Much of the dorsal surface is covered by fine tubercles, which appear coarser and sparser immediately in front of the preglabellar furrow and on the postocular fixed cheeks.
