The left S3 of one cranidium (Pl. 14, fig. 1) does not reach the axial furrow. The posterior border of one hypostome (Pl. 16, fig. 14) is irregularly rounded and spineless; it may be a healed injury. One pygidium (Pl. 18, fig. 23) has a very small, irregularly shaped terminal piece. The axial furrow is impressed over the left side only of the sixth pleurae of one pygidium (Pl. 19, fig. 2).
