Synopsis Coccosteus cuspidatus is shown to be the correct name for the arthrodire commonly referred to as Coccosteus decipiens. An almost complete account of the osteology of this species is given and aspects of the restored head, thoracic armour, fins and posterior unarmoured region, the dermal ornamentation, neuromast system and musculature are discussed; the snout, dermal bones of the palate and neural endocranium receive special treatment in view of the part these structures have played in the interpretation of the relationships of the Arthrodira. Changes in the proportions of certain bones during growth are noted and the mode of life is considered. The family Coccosteidae is redefined; the genus Coccosteus and the type species C. cuspidatus are defined and consideration is given to other species included in this genus.

Synopsis It is confirmed that the type species of the genus Glyptoscorpius Peach 1882 is a subjective synonym of Adelophthalmus Jordan and Meyer 1854. Species which have been referred to Glyptoscorpius are reviewed and their present taxonomic position defined. Cyrtoctenus gen. nov., type species Cyrtoctenus peachi sp. nov., is designated to accommodate forms bearing five pairs of specialised abdominal appendages of which the first is comb-like. Four species of Cyrtoctenus from Devonian and Carboniferous rocks in Scotland, England, Belgium and Czechoslovakia are recognized. The structure and affinities of these forms are discussed with special reference to the comb-like appendages and their ornamentation in relation to these features in other arthropods. In particular the development of filaments and fulcra from different types of scales is discussed. The characters of the new genus are found to be so distinctive as to require the creation of the new order Cyrtoctenida for its accommodation.

Synopsis A detached sporophyl and megasporangium of Mazocarpon pettycurense Benson is described. It formed twelve megaspores. Achlamydocarpon scoticum sp. nov. is described from detached sporophylls and megasporangia. The latter opened by means of three slits in the distal region so making pollination possible. A specimen of Cystosporites devonicus Chaloner and Pettitt is recorded from ash beds at the base of the Cementstone Group.
