Cephalon widest (tr.) across anterior of alae. Large ovoid glabella, anteriorly steeply-sloping with prominent tubercles straddling crest. Tubercles on dorsal surface of eye lobe, occipital ring and internal rim. Alae inflated and moderately large. Alar depression deep and alar and preglabellar furrows well defined. Shallow pitting on post ocular genal area. Narrow (sag.) brim, narrowing moderately posterolaterally (brim width ratio 0.64) with moderately large perforations decreasing in size distally. In lateral view, external rim curves slightly upwards and profile of internal rim weakly wave-like.

are that NHMUK It 29239, has a slightly wider (tr.) cephalon with the widest point being across the midpoint of the glabella rather than across the anterior edge of the alae. Also, the eye lobes are set a little closer to the axial furrow and the tubercles on the glabella are fewer and finer and absent on the dorsal surfaces of eye lobes. The brim differs too, having a brim width ratio of about 0.75 rather than 0.65, and the genal area is finely perforated with the cuticle surrounding the perforations being lighter in tone than elsewhere on the genal area (see
