). Ŋe first (anteriormost) is relatively narrow and slightly inclined posteriorly; the dorsal tip of the bone does not contact the supraorbital bone, and consequently the orbital rim is not closed. Ŋe second is relatively large and trapezoidal; the maximal depth is nearly equal to its length. Ŋe posterodorsal margins of the first and second infraorbital bones contribute the anterior margin of the orbit. Ŋe third to fissh infraorbitals are relatively small and rectangular or trapezoidal, forming the ventral margin of the orbit. Ŋe sixth, located at the posteroventral corner of the orbit, is large and nearly pentagonal with a convex posterior margin. Ŋe seventh is small and trapezoidal, having a depth 1.5 times its length. Ŋe last (eighth) infraorbital is slightly deeper than long, being the smallest one of the infraorbital series. Ŋe infraorbital sensory canal, marked by several pores, runs longitudinally through the anterior two infraorbitals near their ventral borders, traverses the third to fissh at their middle portions; posteriorly, it extends obliquely upwards and passes dorsoventrally through the remaining infraorbitals, and finally enters the dermosphenotic.

Ŋe lateral line pierces the lateral portion of the post-temporal and extends posteriorly through the dorsal portion of the supracleithrum. Ŋe large cleithrum has a dorsal arm longer than its anterior arm; the complete shape of the bone is still unknown because of the lateral coverage of the subopercle and branchiostegal rays. Ŋere are two postcleithra associated with the cleithrum; the upper is trapezoidal, slightly deeper than the supracleithrum, and the lower is short and nearly rhomboidal. Ŋe posterior margins of the supracleithrum and postcleithra are serrated (

, 12 scales are present on each side of the body in the 9th vertical row, including four and seven scales above and below the lateral line, respectively. Seven or eight rows of inverted scales are present posterior to the hinge line in the caudal region; the last row of inverted scales consists of only three small scales (Fig. 7F). Ŋe lateral line scales in the anterior flank region are deepest with a ratio of depth-to-length being about 2. Ŋe body scales gradually become shorter dorsally, ventrally, and posteriorly. Five to six well-developed serrations are present on the posterior margins of anterior scales, and the counts gradually reduce in those of posterior scales. Scales along the dorsal ridge anterior to the dorsal fin are nearly heart-shaped with no distinct posterodorsal spine. Moreover, there is an enlarged dorsal scute anterior to the first epaxial basal fulcrum of the caudal fin. Ŋe peg-and-socket articulations between scales are present, as commonly in other early holosteans.
