Two new families, one new genus and six new species belonging to the orders Katoporida and Thelodontida are described from the Upper Silurian. Seven taxa are re-described. Scattered scales of Loganellia cuneata (Gross, 1947), Paralogania ex gr. martinssoni (Gross, 1967), Paralogania menneri n. sp., Valiukia flabellata n. gen., n. sp., Phlebolepis elegans Pander, 1856, Thelodus visvaldi n. sp., Thelodus matukhini n. sp., Thelodus ex gr. schmidti (Pander, 1856), Thelodus sp. indet. and Lanarkia? sp. are characteristic for the Ludlow part of the sequence (Ust-Spokojnaya Formation of October Revolution Island and its analogue on Pioneer and Komsomolets islands). Thelodus parvidens (?), Loganellia cuneata, Paralogania wilsoni n. sp., P. kachanovi n. sp., Paralogania sp. cf. P. borealis (Karatajūtē-Talimaa, 1978), Goniporus alatus (Gross, 1947) and Nikolivia elongata Karatajūtē-Talimaa, 1978 are distributed in the sections of Krasnaya Bukhta Formation on October Revolution Island and coeval strata of Pioneer Island (Pridoli). Thelodus visvaldi n. sp. is also present in Wenlock of Pioneer Island.</mods:affiliation>

Transitional scales have oakleaf-like configuration and crown surface convex. Trunk scales anteriorly smooth in outline. Lateral portions of the crown are wide, medial crown plate smooth or with a very shallow longitudinal groove. There occur three to four proximally wide spines postero-laterally of the crown and one beneath the posterior crown apex. Dentine tubules very fine, hardly branching, and situated closely to each other. They do not form lacunae-like structures. Pulp canals present. Dentine canals start from the pulp canal. Aspidine layer in the base is thin.</paragraph>
