The skull roof is formed by one dermosupraoccipital and paired frontals, parietals and dermopterotics. There is no temporal fenestra. The frontal is short and rather narrow, except in its posterior part. It covers the orbital area and exceeds this region only a little anteriorly and posteriorly. The dermosupraoccipital is small and the occipital region is conical in shape. The parietal is triangle-shaped, with a broad ventral margin and a pointed upper corner. The bone is devoid of a brush-like process. The dermopterotic is deeper than broad. A small supratemporal (= extrascapular) is located behind the parietal on the

The neural and haemal spines bear an anterior sagittal flange, except the few ones preceding the epichordal and hypochordal pieces. The neural and haemal arches are well developed, but they do not completely surround the notochord. At the level of the first vertebrae, the neural arches are simply in contact. At the end of the abdominal region and in the caudal region, most neural and haemal arches present a more complex contact by means of one single, small postzygapophysis.</paragraph>

CLC S-1098 are incomplete. The dorsal fin begins just after the dorsal apex. Each dorsal pterygiophore bears a ray. The first ray is reduced to a short spine. The two following rays are long, segmented and pointed. The remaining dorsal rays are segmented and branched. The origin of the anal fin is located at a more posterior level than the dorsal one. The first anal pterygiophore is short and bears a small, spiny ray. The second and the third pterygiophores support longer, segmented and pointed rays. The other anal rays are segmented and branched.

The caudal skeleton is composed of 4 or 5 epichordals, 10 or 11 hypochordals and 2 urodermals. Epichordals and hypochordals are rather long. The seventh, eighth and ninth hypochordals are slightly broadened, but there is no real hypertrophy.</paragraph>
